About this tool
Check cabin and check-in bags against Singapore Airlines weight-concept and Americas piece-concept allowances and the 115 cm cabin rule.
This checker measures your bags against Singapore Airlines' published cabin and check-in limits and reports how many kilograms or pieces you are over. Two systems run in parallel on SQ: most of the network uses a weight concept, where one total figure — 25 kg on Economy Lite up to 50 kg in First and Suites — covers every checked piece together, while journeys to and from the Americas switch to a piece concept of 2 × 23 kg in Economy and 2 × 32 kg in Business and above. Cabin baggage is judged on linear dimension: one 7 kg piece whose three sides add up to no more than 115 cm.

115 cm total is checked, so a bag that passes a generic 55 × 38 × 20 test is not wrongly cleared.
Weight-concept and Americas piece-concept routes are modelled separately, not averaged.
Business, First and Suites are judged on the 14 kg two-piece total the airline actually publishes.
On most routes it is a total weight shared across all your bags: 25 kg on Economy Lite, 30 kg on Economy Standard, 35 kg on Economy Flexi and Premium Economy, 40 kg in Business and 50 kg in First and Suites. To and from the Americas the allowance changes to counted pieces instead — 2 bags of 23 kg in Economy and Premium Economy, 2 bags of 32 kg in Business, First and Suites.
The sum of length, width and height must not exceed 115 cm, and the piece must weigh no more than 7 kg in Economy and Premium Economy. Business, First and Suites may carry two pieces on the same 115 cm size rule with a combined weight of 14 kg rather than a separate limit on each bag.
Passengers travelling together on the same booking can normally have their weight allowances pooled at check-in on weight-concept routes, so a 20 kg bag and a 40 kg bag can clear a 2 × 30 kg pool. Pooling never lifts the 32 kg limit on any one piece, and it is applied at the airline's discretion, so ask at the counter rather than relying on it.
A single checked piece must stay within 158 cm of length plus width plus height and must not weigh more than 32 kg. The 32 kg figure is a manual-handling ceiling, so buying extra allowance raises the total you may check in but never the weight of an individual bag — anything heavier has to be repacked before the counter will take it.
