Singapore Airlines cabin bag dimensions and bag size

The maximum Singapore Airlines cabin bag size is 21.7 x 15.7 x 7.9 inches, which works out to 55 x 40 x 20 cm. These measurements include wheels, handles, and any external pockets. Gate sizers on Singapore Airlines match the published limits closely, so a bag marketed as "22 inch" can fail if its wheels push the total past 21.7 inches. Always measure your bag packed, not empty.

Singapore Airlines cabin bag weight limit

Singapore Airlines 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 Singapore Airlines charge for cabin bag bags?

No. Singapore Airlines includes a free carry-on bag plus a free personal item on most fares. This applies across standard economy fares.

Singapore Airlines vs Cathay Pacific carry-on

Singapore and Cathay both cap Economy carry-on at 7 kg, so neither gives you more weight than the other. Singapore uses a 115 cm linear sum, while Cathay enforces a stricter 56x36x23 cm box that some soft carry-ons can flex past but hard-shells cannot. In Business, Cathay bumps the single-bag limit to 10 kg, whereas Singapore keeps each of two bags at 7 kg, so Cathay wins if you pack one heavy roller and Singapore wins if you split your load. Both allow a separate personal item in every cabin.
