Enter your item dimensions and suitcase size to check the fit — carry-on limits, checked bag sizes, and packing tips.
Whether it fits depends on measurements most people get wrong.
Item dimensions vs. suitcase interior dimensions
Item: Varies — measure your specific item
Space: Carry-on interior: ~20" × 13" × 8". Large checked: ~27" × 18" × 11"
Actual clear openings are usually 1–2″ smaller than the labeled size.
Your exact dimensions probably aren't "standard." Small measurement errors cause big problems — 1 inch can be the difference between fitting and getting stuck.
Verdicts are calculated by comparing all 6 item orientations against the space dimensions using verified building code standards. See our methodology

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.
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.
