FREE TOOL / ONE BIN AT A TIME

The opening is part of the fit.

Compare a complete bin’s outside dimensions with a clear opening and a clear interior. Keep the same orientation through both.

This is a straight-in, axis-aligned geometry check—not a weight, mounting, restraint or driving-readiness assessment. It assumes a clear aligned passage and cavity. No diagonal insertion, flexible materials or hidden obstacles are modeled.

The calculator needs JavaScript. On paper, compare the oriented bin width and height with the opening, then its width, depth and height with the interior. Each dimensional difference must meet your selected total spare. Keep the same orientation throughout.

Changing units does not convert the numbers. Re-enter all measurements in the chosen unit. Defaults are fictional, not product specifications.

01 / Clear opening

Opening width (in)

Opening height (in)

02 / Usable rectangular interior

Inside width (in)

Inside depth (in)

Inside height (in)

03 / Complete bin outside dimensions

Original length (L) (in)

Original width (W) (in)

Original upright height (H) (in)

Include the lid, rim, handles and other projections in the stored configuration. These inputs describe one rigid bounding box.

04 / Comparison assumptions

Required total spare per dimension (in)

Total dimensional difference, not spare on each side. Your choice—not a standard. Zero allows geometric equality, not guaranteed handling room.

Include tipped orientations (only if appropriate for this item and contents)

Entries stay in this tab and are not saved automatically. No passing orientation means only that this limited model found none.

Five comparisons for each orientation

Opening width minus bin width, opening height minus bin height, interior width minus bin width, interior depth minus bin depth, and interior height minus bin height must each meet the entered total spare. The same oriented bin is used in every comparison.

Upright mode keeps original H vertical and checks two horizontal rotations. Tipped mode considers all six axis permutations, removing duplicate shapes. It does not rotate the object inside the cavity or search a diagonal insertion path.
