Enter your item dimensions and bag size to check the fit — backpacks, duffels, and tote bags.
Whether it fits depends on measurements most people get wrong.
Item dimensions vs. bag interior dimensions and opening size
Item: Varies — measure your specific item
Space: Daypack: ~20L. Weekend: ~40L. Travel: ~60L. Expedition: ~80L+
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

Frequently asked
A 15" laptop needs a bag with an interior depth of at least 15" and a laptop sleeve at least 10.5" wide. Most 25–30L backpacks fit 15" laptops. Check for a dedicated laptop compartment with padding.

02A 60L duffel typically measures about 26" × 14" × 14" and fits a weekend's worth of clothes, shoes, toiletries, and a jacket. It's the standard gym bag or short-trip size.
