62 linear inches luggage: add L + W + H, then check your airline
A 62 linear inches luggage limit is one number, not three: length + width + height added together must come to 62 inches (157 cm) or less. A 28 × 20 × 12 in suitcase adds up to 60 and clears it; 30 × 21 × 13 in adds up to 64 and does not. Type your bag's three sides below and we do the addition, then compare the total against every airline limit in our verified table.
Measure the packed bag at its widest points — wheels, handles and bulging pockets included.
Which airlines actually use a 62 linear inches luggage limit?
10 of the 20 airlines in our table publish exactly 62 linear inches for a standard checked bag, and 3 more publish 158 cm — the same rule stated in metric. The outliers are worth knowing before you buy a case: Allegiant publishes 80 linear inches, British Airways and Ryanair publish a per-side box instead of a total, and easyJet allows a 275 cm sum. Every number below links to the airline's own baggage page and carries the date we last read it.

A limit published per side is not a linear limit: British Airways measures 90 × 75 × 43 cm on each side, so a long thin bag can pass a 62-inch sum and still fail there. Where an airline publishes both, the tighter one wins.
Linear inches, carry-on inches and personal-item inches are three different rules
The 62-inch sum applies to the bag you hand over at the counter. Your cabin bag is measured side by side instead — 22 × 14 × 9 in on most US carriers — and the free under-seat bag is smaller again. If you are sizing the bag that comes on board with you, the bag fit checker compares all three sides against one airline, and the under-seat size chart covers the free item. Not sure whether your daypack counts as that free item? We answered it with the same table in does a backpack count as a personal item.

Common questions
What does 62 linear inches luggage mean?
It means length plus width plus height, added together, must total 62 inches or less — one number, not three. A 28 × 20 × 12 in suitcase is 60 linear inches and clears it; a 30 × 21 × 13 in bag is 64 and does not. Wheels, handles and side pockets count, because the tape measure does not know what is decorative.
Is 62 linear inches the same as 158 cm?
Effectively, yes: 62 in is 157.5 cm, which airlines round to 157 or 158 cm. That is why European and Gulf carriers publish 158 cm for the same suitcase American carriers describe as 62 linear inches. Both numbers are in the table above with their sources.
What size suitcase is 62 linear inches?
Any bag whose three sides add up to 62 in. In practice the large checked suitcases sold as '28-inch' or '30-inch' sit right on that line — a 29 × 21 × 12 in bag is 62 exactly. Measure the packed bag: a soft case bulges, and the bulge is part of the sum.
What happens if my bag is over 62 linear inches?
You pay an oversize fee, and above a second threshold the bag is refused. JetBlue's published tiers charge from 63 in and stop accepting bags over 80 in; Avelo charges from 63 in; Breeze does not accept anything over 80 linear in. The exact fee is on each airline's page linked above.
Which airline allows the biggest checked bag?
Of the airlines in this table, Allegiant publishes the most generous cap at 80 linear inches — 18 inches more than the usual 62. It is also a paid checked bag on every fare, so the comparison is size, not cost.
