Luggage Space Planner — Packing Cube Volume

Estimate internal suitcase capacity and compare packing cube or item volumes. Identify individual oversized items without promising a physical fit.

Volume is not a fit guarantee. Shape, orientation, rigidity and packing gaps matter.

How it works

Enter usable internal dimensions rather than external luggage measurements. Add each packing cube or rigid item using a rectangular bounding box, with quantity. PackKit sums those volumes and compares them with the bag’s rectangular estimate. It separately checks whether each item type can fit dimensionally in some orientation. This does not arrange all objects together or solve a three-dimensional packing problem. Curved walls, lining, rigidity, handles, compression and gaps can all reduce practical capacity.

Example

Internal dimensions of 50 × 35 × 20 cm estimate 35 litres. Three cubes at 30 × 20 × 10 cm occupy 18 litres. Add a 3.75-litre toiletry bag and 7.2-litre shoe bag for 28.95 litres, or about 82.7% of that estimate. A long narrow item can exceed an individual dimension even when its volume is small. Leave practical space and try packing the real bag before relying on the plan.

Assumptions and limitations

Volume is not a fit guarantee. Shape, orientation, rigidity and packing gaps matter.

Frequently asked questions

Is my trip uploaded or synced?

No. Lists, settings and checkmarks are saved in this browser only. Clearing site data removes them. Use CSV export or printing for a separate copy.

Are baggage limits live airline rules?

No. Enter the limits for your own ticket and verify them with the operating airline for each flight. Example values are not airline policy.

Does the luggage volume tool guarantee everything fits?

No. It compares rectangular volume and individual dimensions, not the combined spatial arrangement of your belongings.
