🧳 Luggage Size & Volume Calculator
Enter your bag's dimensions to get its volume in litres and linear total — and see whether it fits common cabin or checked-baggage limits.

Limits vary by airline and fare — these are common industry references: cabin bags around 56 × 36 × 23 cm (US legacy) or the IATA ~55 × 40 × 20 cm guideline, and checked bags to a 158 cm (62 in) linear total. Budget carriers (Ryanair, easyJet) and weight limits (cabin ~7–10 kg, checked ~23 kg) differ — always check your airline before you pack. 🔒 In your browser.
How the luggage size & volume calculator works
A bag's capacity is length × width × height (in centimetres, ÷1,000 for litres), and airlines usually judge size by the linear total — the three dimensions added together. The tool computes both, in centimetres or inches, and compares the linear total against common reference limits: roughly 56 × 36 × 23 cm for a cabin bag and a 158 cm (62 in) linear total for checked baggage.
Baggage rules vary by airline and fare, and this checks size only, not weight (cabin bags are often capped around 7–10 kg and checked bags around 23 kg). Budget carriers like Ryanair and easyJet have their own, often smaller, cabin allowances — always confirm your specific airline's limits before you pack.
Frequently asked questions
What size is a standard carry-on?
Commonly around 56 × 36 × 23 cm (22 × 14 × 9 in) on US full-service airlines, or the IATA guideline of roughly 55 × 40 × 20 cm. Budget and some international carriers allow less, so check your airline.
How many litres is my suitcase?
Multiply length × width × height in centimetres and divide by 1,000. A 55 × 40 × 20 cm cabin bag is 44 litres; the tool computes it for you in cm or inches.
What is the linear dimension of a bag?
The sum of its length, width and height. Airlines quote checked-bag limits this way — most commonly 158 cm (62 inches) total for standard checked baggage.
What is the checked baggage size limit?
A 158 cm (62 in) linear total is the widely-followed standard for a single checked bag, with a typical economy weight limit around 23 kg (50 lb). Premium cabins and some airlines allow more.
Does this check weight too?
No — it checks dimensions only. Weight limits are separate (often ~7–10 kg cabin, ~23 kg checked economy) and vary by airline and cabin, so weigh your bag and check your carrier's allowance as well.
