Thailand Etiquette: Thai Customs, Do’s and Don’ts

Thai social life runs on politeness, calm and consideration for others. Most Thai people are forgiving when foreigners get a detail wrong, but knowing the core customs helps you avoid causing real offence, whether you’re here for a week or have lived in Bangkok for years.

This guide covers the etiquette that matters in everyday life: greetings and the wai, temples, the monarchy, public behaviour, the BTS and MRT, dining, bargaining, tipping, dress, visiting a Thai home and attending a funeral. Start with the quick-reference table below, then jump to the section you need.

Thai Etiquette at a Glance

Greetings and the Wai

The wai (ไหว้) is the traditional Thai greeting: palms pressed together, fingers pointing up, with a slight bow of the head. It’s used to say hello, goodbye, thank you and sorry, and to show respect. You’ll also see Thai people wai when they pass a temple or spirit house, sometimes from the back of a moving bus.

You don’t need to initiate a wai as a foreigner. A smile and a polite sawasdee khrap (สวัสดีครับ) if you’re a man, or sawasdee kha (สวัสดีค่ะ) if you’re a woman, works in almost every situation. Although it’s usually spelled sawasdee, it’s pronounced sawatdee. The same polite ending turns thank you into khop khun khrap or khop khun kha (ขอบคุณครับ/ค่ะ).

When to Wai (and When Not To)

The wai follows social hierarchy. The younger or more junior person usually wais first, and the senior person returns it, often with a smaller wai or a nod. The height of the hands signals the level of respect:

• Friends and people of similar age: fingertips around chin level
• Older people, teachers and superiors: fingertips around nose level, with a slightly deeper bow
• Monks and Buddha images: fingertips near the forehead

In practice:

• Return a wai when someone of similar or older age offers you one. Your technique doesn’t need to be perfect.
• Wai older people, especially when meeting a partner’s parents or grandparents. This is one situation where initiating a wai is appreciated.
• Service staff in hotels, restaurants and shops may wai you as part of their job. A smile and a nod are enough, although returning the wai is always welcome.
• Don’t initiate a wai to children or to people clearly junior to you. If a child wais you, a smile and a nod are the natural response.
• Monks don’t return a wai to laypeople.
• If your hands are full, a nod or slight bow is fine.

Addressing People: Khun, Phi and Nong

Thai people are addressed by their first name or nickname, not their surname. Most Thais have a short nickname (chue len) that they use day to day, such as Nok, Ploy or Bank, and many will introduce themselves that way.

• Khun (คุณ) is the polite, all-purpose title for adults, used before a first name or nickname: Khun Ploy. Never use it with your own name.
• Phi (พี่) means older sibling and is used for anyone older than you, from colleagues to friends: Phi Nok.
• Nong (น้อง) means younger sibling and is used for people younger than you.
• Lung (ลุง, uncle) and pa (ป้า, aunt) are friendly, respectful ways to address older street vendors and neighbours.

At work, colleagues often use phi or nong with a nickname rather than khun. If you’re unsure which form someone prefers, ask. It’s a normal question and people will appreciate it.

Temple Etiquette

Thailand’s temples (wat, วัด) are active places of worship as well as landmarks, and visitors are welcome at almost all of them.

The essentials: cover your shoulders and knees, take off your shoes before entering temple buildings, and keep your voice down. Most smaller temples are free to enter; the big tourist temples in Bangkok charge foreigners an admission fee.

For the temples most worth visiting, see our guide to Thailand’s most beautiful temples.

What to Wear to a Thai Temple

• Cover your shoulders and knees. A T-shirt with sleeves and long trousers or a skirt below the knee works everywhere.
• Avoid see-through fabrics, very tight clothing, ripped jeans and leggings worn as trousers.
• A light scarf or sarong is useful for covering up at smaller temples, but a top with sleeves is the safer choice at stricter sites.
• Remove hats and sunglasses when you enter a temple building.

The Grand Palace and Wat Phra Kaew (Temple of the Emerald Buddha) enforce the dress code far more strictly than other temples, because Wat Phra Kaew is the royal chapel. Staff at the gate will stop you if you’re not covered; there’s a clothing rental counter near the entrance, but queues can be long in high season. Dress correctly before you leave home.

Shoes, Photos and Buddha Images

• Take off your shoes before entering the ordination hall (ubosot) or prayer hall (viharn). A row of shoes outside the door is the signal.
• Step over the raised threshold of a temple doorway rather than on it. Traditionally, it’s believed to be home to a guardian spirit.
• Inside, sit with your legs tucked to one side so your feet point away from the Buddha image. Don’t sit cross-legged facing it, and never stretch your legs out towards it.
• Photography is usually allowed in temple grounds but sometimes not inside halls. Follow the signs.
• Don’t touch or climb on Buddha images or religious structures. Photos in front of a Buddha image are common, including by Thai visitors, but keep them respectful: sit or kneel rather than pose playfully, make sure your feet don’t point towards the image, and don’t get in the way of people who are praying.
• If you walk around a chedi (stupa), go clockwise, keeping it on your right.

Monks, Donations and Ceremonies

Monks follow strict rules of conduct, and a few of them affect visitors directly:

• Women should not touch a monk or hand anything to him directly. Place the item on a table or cloth in front of him, or ask a man to pass it on.
• On buses, the BTS and the MRT, women shouldn’t sit directly next to a monk. Priority seats are partly reserved for monks for this reason.
• Keep your head lower than a seated monk’s where practical, and don’t point your feet towards him.

Donations are always voluntary. You’ll find donation boxes throughout most temple grounds, and giving is a common way for Thai people to make merit (tham bun, ทำบุญ).

If you arrive during a ceremony or chanting, lower your voice, silence your phone and watch from a respectful distance unless you’re invited to join. Avoid walking directly in front of people who are praying. 

Respecting the Thai Royal Family

The Thai monarchy is deeply respected in Thailand, and it’s also protected by one of the strictest laws of its kind in the world. Under Section 112 of the Thai Criminal Code, known as lèse-majesté, defaming, insulting or threatening the King, Queen, Heir-apparent or Regent carries a prison sentence of three to 15 years per count. The law applies to foreigners as well as Thai citizens, and it covers what you post, share and comment on online, not just what you say in person.

In practice:

• Don’t make jokes, critical comments or disrespectful gestures about the royal family, in person or online. This includes liking, sharing or commenting on other people’s posts.
• Treat royal portraits with respect. You’ll see them in homes, offices, shopping malls and along major roads.
• Don’t step on Thai banknotes or coins, which carry the King’s image. If money falls and starts blowing or rolling away, stop it with your hand rather than your foot.
• A royal anthem tribute plays before films in Thai cinemas. When the screen asks the audience to stand, it’s respectful to do so.
• Stop for the national anthem, played daily at 08:00 and 18:00 in parks, some stations and other public places. People stand still until it finishes; in Lumphini Park, joggers stop mid-run.
• If a royal motorcade passes, roads may be closed for a short time. Wait patiently.

Keeping Calm and Saving Face

Thai social life values calm, politeness and avoiding confrontation. The single most useful rule: never lose your temper in public. Raising your voice rarely solves anything in Thailand, and it usually makes the problem harder to fix. A few Thai concepts explain why.

Saving face. “Face” (na, หน้า) is a person’s dignity and standing in the eyes of others. Publicly criticising, correcting or embarrassing someone causes them to lose face, which is taken seriously even over small things. If you need to raise a problem or correct someone, do it calmly and in private where possible. The flip side is giving face: praising someone in front of others is appreciated.

Jai yen: keep a cool heart. Jai yen (ใจเย็น) means staying calm and composed, especially under pressure. Its opposite, jai rawn (ใจร้อน, hot-hearted), describes someone who is impatient or quick to anger, and it isn’t a compliment. If you hear someone say “jai yen yen”, they’re telling you, or someone else, to calm down.

Kreng jai: not wanting to impose. Kreng jai (เกรงใจ) is a strong reluctance to inconvenience or disappoint others. It explains why Thai people may not ask for help, may avoid saying no directly, or may agree to something they’re not sure about. Answers like “maybe”, “not convenient” or “I’ll check” can be a polite no. For residents, this matters at work and with landlords, contractors and staff: ask open questions and confirm important details rather than relying on a quick yes.

Mai pen rai: let small things go. Mai pen rai (ไม่เป็นไร) means “never mind” or “it’s fine”, and you’ll hear it constantly. It reflects an attitude of not dwelling on minor mistakes or inconveniences. Using it yourself, when someone apologises or something small goes wrong, is a simple way to show goodwill.

A smile doesn’t always mean happy. Thai people often smile in awkward, tense or embarrassing situations, not just friendly ones. If someone smiles while you’re explaining a problem, it usually signals discomfort or a wish to keep things calm, not amusement at your expense.

Patience goes a long way. Things may not always happen as quickly as you’re used to, whether in a shop, a government office or a condo building. A friendly manner, a smile and a little patience will get you further than insisting.

BTS and MRT Etiquette

Bangkok’s BTS Skytrain and MRT are clean, orderly and busy, and regular passengers expect everyone to follow the same unwritten rules. Most of them come down to one idea: keep the noise down and give others space.

• Queue at the marked lines on the platform, and let passengers get off before you board.
• Keep conversations quiet, avoid phone calls where possible, and always use headphones for music or videos.
• Don’t eat or drink on trains or in the paid areas of stations. Finish your food or drink before you pass through the gates.
• Durian isn’t allowed on the BTS or MRT. You’ll see the no-durian signs at station entrances.
• Offer priority seats to monks, older passengers, pregnant women, parents with small children and people with disabilities. Women should also avoid sitting directly next to a monk.
• Take off your backpack in crowded carriages and hold it low or put it between your feet. Move large bags out of the doorway.
• Don’t lean against the poles or block the doors. Move into the carriage so others can get on.

📰 Worth knowing: In July 2026, a group of foreign students on a school trip were filmed talking loudly on a crowded BTS train. When a Thai passenger asked them to lower their voices, some responded with insults and an obscene gesture. The video went viral and caused a huge public uproar in Thailand, leading to apologies from the students and a statement from their country’s embassy. Police fined the students for public insult. Being loud is rarely a legal issue, but turning a polite request into a confrontation can be.

Head, Feet and Personal Space

In Thai culture, the head is regarded as the highest and most respected part of the body, and the feet as the lowest. Most of the customs below follow from that simple idea.

• Don’t touch anyone’s head, including patting someone on the head in a friendly way. With young children, avoid it unless you know the family well. If you touch someone’s head by accident, a quick apology is enough.
• Don’t point your feet at people, Buddha images or household shrines. When sitting on the floor, tuck your legs to one side.
• Keep your feet off tables, chairs and other surfaces where people sit or put things, including seats on public transport.
• Don’t use your foot to point at something, push a bag along or hold a door open.
• Avoid stepping over people who are sitting or lying on the floor, or over food laid out on a mat. Walk around instead.
• Point at people with your whole hand rather than one finger, which can come across as rude.
• Keep physical contact with people you don’t know well to a minimum. Holding hands in public is fine, but kissing and more intimate displays of affection are frowned upon.

Dining Etiquette

Eating is central to Thai social life, and meals are relaxed rather than formal. You’ll even hear “kin khao reu yang?” (กินข้าวหรือยัง, have you eaten yet?) used as an everyday greeting. There are no complicated table manners to learn, but a few habits help.

• Share dishes. In a group, dishes are ordered for the table and shared, with rice served individually. Take a small portion onto your own plate and go back for more as you eat.
• Use the serving spoon provided when taking food from shared dishes, not your own spoon.
• Thai food is eaten with a spoon and fork. Chopsticks are mainly used for noodle soups and dishes with Chinese influence.
• Eat sticky rice with your hand. With northern and northeastern (Isan) food, roll a small ball of sticky rice with your right hand and use it to scoop up food or dip it into sauces.
• Taste before you season. Noodle stalls and many casual restaurants have a condiment set on the table, usually fish sauce with chillies, dried chilli flakes, sugar and chilli vinegar. Adjusting the flavour to your taste is normal and not an insult to the cook.
• Wait for the host or the most senior person to start eating when you’ve been invited to a meal, and offer the last portion of a shared dish to others before taking it.
• When eating with Thai colleagues or older friends, the most senior person or the one who invited you will often pay. Offer to contribute, but don’t insist. Among younger friends, splitting the bill is common.

Bargaining in Thailand

Bargaining is normal at markets and independent stalls in Thailand, but not everywhere, and it should always stay friendly. The aim is a fair price for both sides, not the lowest price possible.

• Know where to bargain. Markets, street stalls and some independent shops usually have room to negotiate, especially when you buy several items. Prices in shopping malls, department stores, supermarkets, convenience stores and chain shops are fixed, and so are items with printed price tags.
• Ask politely. “Lot dai mai khrap?” or “lot dai mai kha?” (ลดได้ไหมครับ/คะ, can you give a discount?) with a smile is the easiest way to start. Many vendors will type a price on a calculator or phone, and you can reply the same way.
• Keep your expectations realistic. Discounts at markets tend to be modest. Offering half the asking price on an item that’s already cheap can come across as rude.
• Only bargain if you intend to buy. If the seller accepts your price, it’s good etiquette to go through with the purchase.
• Don’t push too hard. Criticising the product to force the price down, or arguing over a few baht, turns a friendly exchange into a confrontation.
• Accept “no” gracefully. If the seller won’t go lower, either pay the asking price or thank them and walk away.
• Agree the fare before you ride. With tuk-tuks and taxis that won’t use the meter, settle the price before you get in, not at the end of the journey. A tuk-tuk ride that seems unusually cheap is often a warning sign: read about the tuk-tuk detour scam.

Tipping in Thailand

Tipping in Thailand is appreciated but rarely obligatory, and there’s no fixed percentage to follow. Tip in cash, in baht, and when you want to reward good service. Always check your bill first: many mid-range and upmarket restaurants already add a 10% service charge.

Dress Code in Thailand

Everyday dress in Thailand is relaxed, especially in Bangkok and tourist areas. Light, breathable clothing is the practical choice in the heat, and casual wear is fine for sightseeing, shopping and most restaurants. The main rule is to dress for the setting: what works at the beach doesn’t work in town, and some places expect you to cover up. For temples, see the dress code in our temple etiquette section above.

Beachwear, Malls and Rooftop Bars

• Keep swimwear for the beach and pool. Put on a shirt or cover-up before walking into shops, restaurants or the street, and don’t go shirtless away from the beach.
• Topless sunbathing isn’t accepted on Thai beaches, even in tourist areas.
• Casual clothing is fine in shopping malls and most restaurants.
• Many of Bangkok’s rooftop bars and upscale restaurants have their own dress codes, and staff at the door do turn people away. At Lebua at State Tower (The Dome, home of Sky Bar), the bars and restaurants are smart casual: tailored shorts are fine, but athletic wear, swimwear, sleeveless shirts for men, flip-flops and beach slippers are not. Its fine-dining venues are stricter, with collared shirts and long trousers required for men. The rules apply to children too. Dress codes vary between venues, so check the website before you go.
• Away from Bangkok and the main tourist areas, slightly more modest clothing is appreciated.

Government and Immigration Offices

When visiting an immigration office, a government department or a court, dress neatly and modestly. Many offices post signs at the entrance listing what isn’t allowed, typically shorts, sleeveless tops, very short skirts and flip-flops. You don’t need a suit, but long trousers or a knee-length skirt, a shirt with sleeves and closed shoes or smart sandals are a safe choice.

For residents, this applies to every visit: visa extensions, 90-day reports, re-entry permits and work permit appointments. Dressing neatly shows respect for the officials handling your case, and it’s one small thing you can control in a process that can otherwise feel unpredictable.

For business meetings, formal occasions or meeting a partner’s family for the first time, dress a step smarter than you would for everyday sightseeing.

Visiting a Thai Home

Being invited into a Thai home is a sign of friendship, and hosts are generally relaxed about guests getting details wrong. Households range from very traditional to completely informal, so watch what your hosts do and follow their lead. A few customs apply almost everywhere.

• Take off your shoes before you go inside. Shoes by the door are the signal, and this often applies to condos as well as houses.
• Greet older family members first. A wai is appreciated when you meet a partner’s parents or grandparents for the first time, and it’s one of the few situations where initiating a wai as a foreigner is expected. See the greetings section above for how.
• Bring a small gift if you’ve been invited for a meal or are meeting the family. Fruit, sweets or pastries from a good bakery are safe choices. Hand it over with your right hand or both hands.
• Accept food and drinks when they’re offered. Hosts may offer repeatedly; taking a little is polite, but you don’t need to eat more than you want.
• Offer to help clear the table or wash up. Your host may well decline, but the offer is appreciated.
• Keep your feet in check. Sit with your feet tucked away from people and from the family shrine, and never put your feet on tables or furniture.
• Treat religious objects with respect. The Buddha shelf inside and the spirit house outside are not decorations: don’t touch or move anything on them, and don’t point your feet at them.

Attending a Thai Funeral

You don’t need an invitation to attend a Thai Buddhist funeral. If you knew the deceased or their family, or you’re joining a friend or colleague, it’s normal to go and pay your respects. Wear black, white or a combination of the two, and avoid bright colours. Funerals usually take place at a temple over several evenings of chanting before the cremation, and you don’t need to attend every evening

Guests usually give the family money in an envelope to help with funeral and merit-making costs. Every funeral is different and nothing is mandatory, but 500 to 1,000 baht or more is common, depending on how well you knew the deceased and their family. Instead of money, some guests send a funeral wreath or donate supplies to the temple, such as electric fans.
