How a baseplate becomes an organizer
Gridfinity already describes a drawer exactly — a baseplate is n by m cells and every bin covers whole cells. WhichDrawer's layout is the same thing: a grid of rows and columns where cells can be merged into larger drawers. So nothing is approximated. The mapping is one to one:
| Gridfinity | WhichDrawer | Notes |
|---|---|---|
| Baseplate (e.g. 6 × 4) | Organizer with a 6 × 4 layout | Photograph the open drawer from above for the cover |
| One 42 mm cell | One grid cell | Custom layouts go up to 12 × 12 — split a bigger baseplate in two |
| 1 × 1 bin | One drawer | Named, coloured, numbered |
| 2 × 1, 2 × 2, 2 × 4 bin | Merged cells | Select the cells, tap Merge — items stay with the surviving drawer |
| What's in the bin | Items with photos, quantities and custom fields | Thread, length, bin height — whatever you sort by |
| Bin label | QR label sized to the label shelf | Scan it with the app or the Camera app to open the bin |
Baseplate templates
The Templates tab has a Gridfinity filter. Apply one to an organizer and the grid is drawn for you; merge cells afterwards to match the bins you actually printed. Dimensions are the baseplate footprint at 42 mm pitch.
Gridfinity 4 × 4 Baseplate
Sixteen cells, each its own bin. Merge pairs for the screwdriver bits and the longer bolts.
Gridfinity 5 × 5 Baseplate
The largest square grid a 210 mm drawer takes without trimming the baseplate.
Gridfinity 6 × 4 Baseplate
The classic wide drawer: six across the front, four deep.
Gridfinity 6 × 6 Baseplate
Thirty-six cells — the point at which a map stops being optional.
Gridfinity 6 × 4 Mixed Bins
Already merged: a 2 × 4 and a 2 × 2 along the back, 1 × 2 bins in the middle, 1 × 1 along the front.
Gridfinity 6 × 6 Mixed Bins
Big bins for the deep stuff, a front row of singles for the fiddly stuff.
Labels that fit the label shelf
From any organizer, Print Labels makes a PDF with one QR label per bin. The Gridfinity presets are 35 × 12 mm for a 1u bin and 77 × 12 mm for a 2u bin — the widths the label-shelf generators use — laid out as cut-out strips on A4, with the bin's name, its colour and a code that opens the bin in the app. Scan with WhichDrawer's scanner or the iPhone Camera app and the bin's contents come up. Avery 5160 sheets, Brother DK-11201 rolls and plain A4/Letter grids are there too for the cabinets that aren't Gridfinity.
Labels say what; the index says where
A label answers “what's in this bin?” when you're already at the drawer. The app answers “which drawer, and which bin?” from across the shop — or from the hardware store, when you can't remember whether you already have M4 × 12 socket heads. Hold a mystery part up to the camera and AI search returns the closest match and its bin.
What else comes along
- Low-stock and reorder lists for consumables — inserts, magnets, nozzles — with a minimum per item.
- Household sharing, so everyone at the bench can see each other's drawers.
- Custom fields for thread pitch, length, material, bin height.
- CSV import and export, if you already keep a spreadsheet of bins.
The longer version, with screenshots of a real fastener drawer, is in the Gridfinity inventory guide. For commercial cabinets and their grid sizes, see the Drawer Organizer Guide.
