Gridfinity, sized
to your drawer.

Measure the space. Get the plate that fits. Lay out the bins.

Gridfinity is a 42 mm grid, so the only real question about any drawer is how many whole cells actually fit inside it. DrawerCraft measures the space with your camera — width, then depth, then height, two taps each — and answers that question exactly, along with the tallest bin the drawer will still close on.

Then it hands you the plate. Drag standard bins onto it, rotate them, label what goes in each one, or auto-fill the whole thing with the largest bins that will fit.

What it does

Four steps, no guesswork.

Everything the app knows comes from the published Gridfinity spec — 42 mm cells, 7 mm height units, 41.5 mm bin footprints — applied to the drawer you actually have.

Measure with the camera

A guided AR flow captures width, then depth, then height — two taps per dimension. Manual entry in mm or inches is always there as a fallback.

Get the plate that fits

The largest baseplate that drops in, the tallest bin in 7 mm units, how much space is left over — and what to do with the leftover.

Lay out the bins

Drag standard sizes onto the plate, rotate them, change their height, or auto-fill with the biggest bins that fit. Nothing overlaps, nothing hangs off the edge.

Design custom bins

Paint any connected shape on the grid — an L to wrap a corner post, a U around a fixed divider — and save it to your library.

Never lose it again

Catalogue what lives in every bin, then search it from anywhere in the app instead of opening five drawers to find one tap.

Plan the print run

Work out how baseplates split to fit your printer's bed, how many runs the job takes, and how many parts you're committing to.

The detail most calculators miss: a bin's 4.75 mm interlocking base sits inside its first height unit, so a 3U bin stands 21 mm, not 25.75 mm. Add a stacking lip and it's 25.4 mm. DrawerCraft calls that out separately, because it's the difference between a drawer that closes and one that doesn't.
