- Tray fit inside drawer: fit_width = drawer_width − 2×clearance, fit_depth = drawer_depth − 2×clearance.
- Outer tray size: tray_width = fit_width, tray_depth = fit_depth, tray_height = min(drawer_height − clearance, target_height).
- Inner usable space: inner_width = tray_width − 2×wall, inner_depth = tray_depth − 2×wall.
- Divider allowance: available_width = inner_width − (compartments−1)×divider.
- Needed width for a group: required = count×(item_width+gap) − gap.
- Depth check: inner_depth ≥ item_length + margin flags long tools.

Drawer measurement and fit tolerances
Accurate drawer measurements prevent trays that bind, rock, or waste space. Measure internal width and depth at the narrowest points, then subtract clearance on both sides. In humid garden sheds, wood drawers can swell, so include extra clearance if seasonal sticking occurs. Height matters for bulky handles and gloves, so keep tray height below the drawer’s usable height and allow easy finger access.
Compartment planning for mixed tools
Garden workstations often store cutlery for harvest, pruners, plant labels, dibbers, and measuring spoons. A compartment layout balances access and separation. Fewer compartments increase capacity for irregular tools, while more compartments improve organization for repeated tasks for fast daily routines. Use allocation weights to dedicate more width to your dominant category, then validate fit using the required-width check.
Width capacity and spacing logic
The calculator estimates required width as count multiplied by item width plus spacing, minus one spacing gap at the end. This matches a single-row packing assumption, which is practical for quick grab-and-go drawers. If you stack items, required width decreases, but retrieval becomes slower. Increase gap for textured handles, wet tools, or when liners add friction.
Depth checks and length safety margins
Long knives or pruners need enough depth so tips do not hit the tray wall. The depth check compares tray inner depth to the longest item length plus a small margin. If the check fails, reduce item length by storing diagonally, choose a deeper drawer, or allocate a dedicated tool bin without end stops. Add a protective guard for sharp edges in garden settings.
Exporting results for purchasing and fabrication
Exporting results supports consistent buying and workshop cutting. The CSV provides numeric dimensions for inventory lists, while the PDF is convenient for printing at a hardware store or sharing with a fabricator. Pair the output with your preferred material thickness and liner choice. When building custom trays, test-fit a cardboard mockup before cutting final plastic or plywood.
FAQs
What clearance should I use for tight drawers?
Start with 0.3–0.5 cm (or 1/8–3/16 in) per side. Increase clearance for wood drawers in humid sheds, warped runners, or liners. If the tray must lift out often, add a little more for comfort.
How do I measure item width accurately?
Measure the widest handle section with a ruler or caliper. Use the largest utensil or tool in that group, not the average. If grips are rubberized or textured, add extra gap to avoid snagging.
Why does a compartment show “Check fit” when I stack items?
The calculator assumes a single row for quick retrieval. Stacking reduces required width, but it also increases tangling and slows access. Treat “Check fit” as a prompt to adjust layout, weights, or storage method.
What if my tools are longer than the tray depth?
Store long tools diagonally, switch to a deeper drawer, or use a dedicated open bin. You can also reduce end walls or add a removable tip guard. Recheck depth after changing the storage orientation.
Can I use this for non-kitchen garden drawers?
Yes. It works well for potting benches, greenhouse carts, seed drawers, and utility stations. Enter counts and dimensions for labels, pruners, scoops, and measuring spoons. Choose fewer compartments for irregular shapes.
How should I validate before buying or cutting material?
Print the PDF and compare against your drawer measurements. Make a quick cardboard mockup at the calculated outer size, then confirm slide-in fit and finger access. Adjust clearance and divider thickness until the mockup feels right.
