The maximum Thai Airways cabin bag size is 22 x 17.7 x 9.8 inches, which works out to 56 x 45 x 25 cm. These measurements include wheels, handles, and any external pockets. Gate sizers on Thai Airways match the published limits closely, so a bag marketed as "22 inch" can fail if its wheels push the total past 22 inches. Always measure your bag packed, not empty.
Thai Airways cabin bag weight limit
Thai Airways limits carry-on bags to 7 kg (15.4 lb). Most domestic check-in counters do not weigh carry-ons, but gate agents can pull bags that look heavy. If your bag is over the limit, expect to be asked to check it, sometimes at a higher gate-check fee.
Does Thai Airways charge for cabin bag bags?
No. Thai Airways includes a free carry-on bag plus a free personal item on most fares. This applies across standard economy fares.

Common Thai Airways carry-on mistakes
- Assuming the 7 kg Economy limit is loosely enforced. Thai weighs bags at check-in and gate.
- Thinking the March 2026 piece-concept change loosened carry-on rules. It primarily affects checked bags, not cabin allowance.
- Treating a laptop backpack as a personal item when it exceeds the small personal item size.
Thai Airways vs Singapore Airlines carry-on
Thai Airways gives Economy 7 kg in a 56x45x25 cm bag plus one small personal item, which is the same 7 kg weight Singapore Airlines allows Economy. The practical difference is enforcement. Thai actively weighs bags at Suvarnabhumi and has tightened allowances in early 2026, while Singapore Airlines is known for a more relaxed gate check on a 115 cm total-dimension bag. Business travelers win more on Thai, where Royal Silk permits 2 cabin bags at 7 kg each versus Singapore Business Class at 2 pieces with a 7 kg each limit as well. If you fly Economy and pack to exactly 7 kg you are fine on either carrier, but Thai is the stricter of the two on weight.
