What are the standard suitcase sizes?

Carry-on: 22" × 14" × 9" exterior (20" × 13" × 8" interior). Medium checked: 25" × 18" × 11". Large checked: 29" × 20" × 13". Always check your airline's specific requirements.

How much can I fit in a carry-on?

A standard carry-on has about 2,000–2,500 cubic inches of usable space. That's enough for 3–5 days of clothes, a laptop, toiletries, and a pair of shoes for most travelers.

Can I pack fragile items in a suitcase?

Yes — wrap fragile items in clothes or bubble wrap and place them in the center of the suitcase surrounded by soft items. Hard-shell suitcases provide better protection than soft-shell for fragile cargo.

Measure smart

What to measure.

Four numbers decide nearly every fit check. Get these right and the rest follows.

01Suitcase interior dimensions — measure length, width, and depth from the inside walls, not the exterior shell
02Suitcase opening width — some suitcases open clamshell (full access) while others have a top-load opening
03Item dimensions with packaging — if wrapping the item in clothes or bubble wrap, add 1–2 inches per side
04Weight allowance — airline carry-on limits are 15–22 lbs; checked bags are 50 lbs; overweight fees apply above that

Don't make these

Common mistakes.

Most “it didn't fit” stories trace back to one of these oversights.

⚠Using the exterior suitcase dimensions — walls, frame, and lining reduce usable interior by 2–4 inches per side
⚠Forgetting about the suitcase structure — hard-shell suitcases have fixed interior depth; soft-shell can flex slightly
⚠Not considering weight limits — packing heavy items in a suitcase may exceed airline weight limits even if they fit by size
⚠Trying to pack rigid items through a narrow opening — if the suitcase has a top-loading design, measure the opening separately
