What should I pack for Thailand?
Start with light clothes, a proper sleeved outfit and loose long trousers for the Grand Palace, comfortable shoes, sun protection, insect repellent and your usual medicines with the required documents. Add rain protection, swimwear or a warmer layer for the places and activities on your route. Decide when you can wash clothes before choosing quantities.
Check your entry date and passport first
Rules change on September 15, 2026. The Royal Thai Embassy in London announces up to 30 days for tourism for British and Irish passport holders and other listed eligible nationalities from that date, with two visa-exempt entries per calendar year under that scheme. Do not use an old blanket “60 days” or “30 days by land, 60 by air” answer. For an earlier arrival, a different passport, repeated visits or a non-tourism purpose, check the rule that applies to you. Read the official visa exemption notice and nationality list, then confirm with the Thai embassy responsible for your application. This page is not an eligibility checker.
- Check passport validity, visa or exemption eligibility, permitted stay, onward travel and any evidence of funds required for your entry category before booking around a maximum stay.
- Keep passport, booking details, first accommodation address and insurance contact information accessible offline. Carry the original documents where required; a phone photo does not replace a passport.
- TDAC is separate from a visa. Non-Thai visitors normally submit the Thailand Digital Arrival Card in the three-day window including arrival day. For September 15 arrival, that window starts September 13. Use the official TDAC website and save the confirmation. A new entry needs a new submission. Transit without passing immigration is an exception; review the official TDAC FAQ for your situation.

Choose clothes for your actual stops
| Your stop | Pack or wear | Check before going |
|---|---|---|
| Bangkok and temples | A sleeved shirt, loose long trousers or a long skirt, comfortable walking shoes and a light layer for strong indoor air conditioning. | For the Grand Palace, a shawl over a sleeveless top is not accepted. Avoid tight, ripped or see-through clothing. A scarf is an optional accessory, not a substitute for compliant clothes. See the Grand Palace's official dress rules; other temples have their own rules. |
| Phuket, Samui and boat trips | Swimwear, a sun shirt, hat, suitable sunscreen, grippy footwear and a dry bag for splash protection. | Check the operator's bag allowance, weather and departure status. A dry bag does not make it safe to enter rough water. Follow park-specific sunscreen ingredient rules; a “reef-safe” label alone does not establish compliance. |
| Chiang Mai and northern hills | A light layer for the city; add warmer clothing and suitable footwear for the elevation, season and tour. | Do not use Bangkok temperatures for a mountain overnight. Check the local forecast and guide's equipment list. A light hoodie is not a guarantee of adequate warmth. |
| Rainy days anywhere | A packable rain shell or poncho, quick-drying clothes, grippy shoes and a separate bag for wet items. | Rain patterns differ between the Andaman and Gulf coasts. Check the Thai Meteorological Department's forecast and warnings for each stop. Rain need not be a short afternoon shower; transport and trails can be affected. |
Medicines, mosquitoes, food and drinking water
Before packing medicines, check their active ingredients in the Thai FDA traveller medicine checker. Controlled drugs have different permission and quantity rules; some are prohibited. Keep original labelled packaging and a prescription or doctor's letter. If a permit is required, the FDA advises applying at least 15 days before arrival. Do not assume a prescription at home makes every medicine legal to bring.
Pack a repellent suitable for your age and circumstances and follow its label. DEET and picaridin are examples; there is no need to insist on one brand. Mosquito protection matters during daytime as well as evening. Clothing can add protection. Arrange a travel-health consultation for your itinerary and personal needs; see CDC's Thailand guidance.
Choose factory-sealed drinking water when a safe supply is uncertain, including for brushing teeth. A reusable bottle is useful only if you fill it with safe water. A basic filter does not reliably remove every pathogen; purification tablets and filters are not interchangeable, and disinfectants do not remove chemical contamination. For remote travel, choose a treatment system for the actual hazard using CDC's water-treatment guidance.
Food served thoroughly cooked and hot is a better choice than raw or undercooked food; a busy stall does not guarantee safety. Check water and ice sources in Bangkok as well as elsewhere. Pack hand-cleaning supplies. Oral rehydration salts can be useful if mixed with safe water in the volume on the packet. Ask a clinician or pharmacist whether any diarrhoea medicine is appropriate for you. Loperamide alone is not recommended with bloody diarrhoea or fever; bismuth subsalicylate has important restrictions, including pregnancy, aspirin allergy and some medicines or medical conditions. Seek medical advice for those symptoms, dehydration or severe/persistent illness. See CDC's travellers' diarrhoea guidance.
How much clothing? Work back from laundry
These are editorial examples, not tested minimums. Count what you wear on the flight as part of the total. Add clean underwear for each day until the next reliable wash, plus a spare; adjust socks, extra tops and swimwear for your activities. Confirm laundry turnaround and drying time instead of relying on a nationwide price or same-day promise.
| Example plan | Starting total | What changes it? |
|---|---|---|
| Four days, city stay | 4 tops, 2 bottoms, 5 underwear; 1 walking pair of shoes. Make one outfit palace-appropriate if needed. | Add a top if you change after hot outdoor days; sandals are optional. |
| Seven days, laundry after day 4 | 5 tops, 2–3 bottoms, 5 underwear; walking shoes and optional sandals. | Five sets bridge the first four days and a laundry day. If washing or drying is delayed, increase the clean-clothing allowance. |
| Two weeks, reliable wash every 4 days | Start with the same washable core as the seven-day example. | Add activity layers and enough drying time; without laundry, recalculate for all days rather than simply reusing this total. |
Check flight luggage and small essentials
- Check every operating airline and fare, including domestic connections, for cabin size, weight, personal-item rules and checked-bag fees. Weigh the packed bag with the outer bag and electronics included. Use the packing-cube weight comparison to see whether added organisers push it over your entered limit.
- Check departure and transfer security rules for sunscreen, repellent and other liquids, plus your airline's power-bank policy. Keep necessary medicines accessible with their documentation. The carry-on packing guide helps organise the final bag.
- Check your accommodation's outlet and your charger's input label. A plug adapter does not convert voltage. Do not plug in a device unless its input rating matches the local supply.
- Carry a practical mix of payment methods and some baht for places that require cash. Read the ATM's displayed fee and conversion offer before accepting. Confirm mobile coverage for your route, phone compatibility, tethering rules and actual data limits before buying a SIM or eSIM; keep essential maps and documents offline.

Build my Thailand packing listFrequently asked questions
- Do I need a visa for Thailand?
- Check your passport, entry date and travel purpose against the Thai embassy rules. A revised exemption scheme takes effect September 15, 2026. TDAC is an arrival form, not a visa or permission to stay.
- Can a scarf replace sleeves at the Grand Palace?
- No. The official dress rules reject a shawl over a sleeveless top. Wear a proper sleeved shirt with loose long trousers or a suitable long skirt; check the venue rules before visiting.
- Should I bring a water filter?
- For ordinary travel, plan a safe drinking-water supply first. A basic filter does not remove all pathogens. For remote travel, match a treatment system to the water hazards and follow its instructions.
- Can I pack five tops for two weeks?
- Only if your activities and reliable laundry schedule make that workable. Count clothes through washing and drying, add a spare, and allow for days when you need to change twice.
- Does this guide forecast my travel dates?
- No. These are planning examples. Check local forecasts and warnings shortly before each stop. The generator can request a short-range forecast when available, but cannot guarantee weather for distant dates.
