How many linear inches is my bag?

Type the length, width and height of your bag. The linear inches calculator adds them up and tells you whether the bag is within the size limit, 62 inches (157.48 cm) by default.

Linear inches: 62. Your bag is 62 linear inches (157.5 cm). Within the limit: Yes.

How to calculate

Adds the length, width and height of a suitcase or box to get its linear inches and centimeters, and checks it against a size limit such as the 62-inch checked bag rule.

Example with the default inputs (Length 26 in, Width 20 in, Height 16 in, Size limit 62 in): Your bag is 62 linear inches (157.5 cm). Within the limit: Yes.

Method: linear inches = length + width + height (in inches); room to the limit = limit − linear inches.

  • Measure the outside of the bag, wheels, handles and pockets included, as airlines do.
  • The default limit is 62 linear inches (157.48 cm), common for checked bags; a bag exactly at the limit is within it, as Delta’s “must not exceed” says. Check your airline’s own limit.

  1. Length 26 in, Width 20 in, Height 16 in, Size limit 62 in gives Linear inches 62, Linear centimeters 157.48, Within the limit? Yes, Room to the limit, in 0.Source: 26 + 20 + 16 = 62 in = 157.48 cm (1 in = 2.54 cm, NIST SP 811); Delta Air Lines, Baggage Policy and Fees: length + width + height must not exceed 62 inches (157 cm), so a bag at exactly 62 in is within the limit, https://www.delta.com/us/en/baggage/overview (retrieved 2026-10-18)
  2. Length 29.53 in, Width 19.69 in, Height 13.78 in, Size limit 62.2 in gives Linear centimeters 160, Linear inches 62.992126, Within the limit? No, it is over, Room to the limit, cm -2.Source: Malaysia Airlines, Checked baggage: each piece must have linear dimensions (length + height + width) of less than 158 cm or 62 in, https://www.malaysiaairlines.com/th/en/travel-info/baggage/checked-baggage.html (retrieved 2026-10-18)
  3. Length 22 in, Width 14 in, Height 9 in, Size limit 62 in gives Linear inches 45, Room to the limit, in 17, Within the limit? Yes.

How it works

  • Linear size = length + width + height, each converted to the same unit first.
  • Linear inches = linear size in inches; linear centimeters = linear size in centimeters (1 in = 2.54 cm exactly).
  • Room to the limit = limit − linear size, in inches and in centimeters. It is negative when the bag is over.
  • Within the limit? shows "Yes" when the room to the limit is 0 or more (a bag exactly at the limit fits), and "No, it is over" otherwise.

The default limit is 62 linear inches, which many airlines use for checked bags. Type your airline's limit to check against it. Airlines word the limit differently: Delta says a bag "must not exceed 62 inches", so exactly 62 inches is within it, while Malaysia Airlines asks for less than 158 cm or 62 in. This page counts a bag exactly at the limit as within it, as Delta does.

Exact arithmetic. Each length is read as the exact decimal you typed, in the unit you typed it in, so the sums are exact.

Rounding. Inches and room in inches show with at most 2 decimals; centimeters and room in centimeters with at most 1, each rounded half up, trailing zeros left off.

Assumptions

  • You measure the outside of the bag, wheels, handles and pockets included.
  • Each side is more than 0 and at most 100 m; the limit is more than 0 and at most 1,000 m.

Worked examples by hand

A 26 × 20 × 16 in suitcase, 62 in limit. 26 + 20 + 16 = 62 linear inches = 62 × 2.54 = 157.48 cm. Room: 62 − 62 = 0 in, so it is within the limit.

A 75 × 50 × 35 cm suitcase, 158 cm limit. 75 + 50 + 35 = 160 cm = 160 ÷ 2.54 = 62.99 in. Room: 158 − 160 = −2 cm, so it is over.

A 22 × 14 × 9 in carry-on, 62 in limit. 22 + 14 + 9 = 45 linear inches, with 62 − 45 = 17 in to spare.

Other questions people ask

How do I calculate linear inches?

Add the length, the width and the height of the bag in inches. A suitcase 26 in long, 20 in wide and 16 in deep is 26 + 20 + 16 = 62 linear inches.

What does 62 linear inches mean?

It means the length, width and height of a checked bag must add up to 62 inches or less. Delta, for example, says the total “must not exceed” 62 inches (157 cm). Many airlines use this limit and charge an oversize fee above it. A 26 × 20 × 16 in suitcase is exactly 62 inches.

Do wheels and handles count?

Yes. Airlines measure the outside of the bag, so include wheels, handles, and full outside pockets. Measure with the bag packed, because a soft bag bulges.

How many linear inches is a carry-on?

A common carry-on size is 22 × 14 × 9 in, which is 45 linear inches. Most airlines set a carry-on limit for each side, not just the sum, so check all three sides too.

How do I convert linear inches to centimeters?

Multiply by 2.54, since 1 inch is exactly 2.54 cm. 62 linear inches is 157.48 cm. Airlines round it differently: Delta writes 157 cm and Malaysia Airlines 158 cm.

What if my bag is over the limit?

The result shows how many inches and centimeters over it is. Most airlines charge an oversize fee for checked bags over 62 inches, up to a larger maximum. Check your airline’s rules before you fly.
