Match your case to airline limits
Overhead sizers vary between carriers, and an oversized corner can mean a gate-check you did not plan for. We list every case by outer bounds so you know what fits before packing. Enter the limits from your boarding pass into our finder, and we show you the exact hard shells and compact bags cleared for that cabin.

How we measure
- The case stands on its wheels with the handle down, and we take it across the widest point in each direction.
- That is what a gate sizer takes too. Numbers on the label are usually the body alone, and the wheels are what get you stopped.
- A case can be turned but not squashed, so we sort both your box and the case largest side first and compare them one to one.
- Soft bags give a little when they are half packed. We do not count on that and neither should you.
Where the numbers stop
Airlines change what they print, and the two carriers on one ticket rarely agree. Take the tighter of the two.
Payment, delivery and returns run through our retail partner, not through us. This site is where the cases are described and measured.
