Few things ruin a trip faster than an excess baggage charge at the airport counter. Airlines state allowances in kilograms, pounds or both, and the numbers do not always match neatly. This guide explains common baggage limits, how to convert them and how to weigh your bags at home, with our KG to LBS Converter and LBS to KG Converter converters.
Common allowances
| Allowance | In kg | In lb |
|---|---|---|
| Typical economy checked bag (piece system) | 23 kg | 50 lb |
| Heavier checked bag (some classes or routes) | 32 kg | 70 lb |
| Typical carry-on | 7 to 10 kg | 15 to 22 lb |
Allowances depend on the airline, route and ticket type. Always check your ticket.
Piece vs weight systems
- Piece system: you may check a set number of bags, each up to a weight limit (often 23 kg). Common on routes to and from North America.
- Weight system: you get a total weight, such as 30 or 40 kg, split across bags as you like. Common on many Gulf and Asian routes.
Weighing at home
A hanging luggage scale is cheap and accurate enough. If you only have a bathroom scale:
- Weigh yourself.
- Weigh yourself holding the bag.
- Subtract.
If your scale shows pounds, convert to kilograms with the LBS to KG Converter converter.
Leave a margin
Airport scales can read slightly differently from yours. Aim for 1 kg under the limit. Food items like mangoes or sweets for family abroad are heavy, so pack them last and weigh again.
Size limits matter too
Bags also have size limits, usually based on length + width + height. Large but light boxes can still be refused or charged. Our Box Size Calculator helps if you are packing items in cartons.
Excess baggage costs
Excess charges are usually per kg or per extra piece and can be high at the airport. Buying extra allowance online before travel is often cheaper.
Quick conversions
For conversions on the spot, remember that 1 kg is about 2.2 lb. See how to convert kg to lbs for the exact method and a full chart.
