THE HOME WORKSHEET / MEASURE FIRST
A measured plan. A clearer fit.
Compare two regular, single-layer arrangements using the space and clearances you specify. The results help you check a layout before buying; they cannot check the door opening or load capacity.
Shelf & Bin Fit Calculator
Use the space you actually have.
Measure the internal shelf and the outside of the bin, including lids and projections. Record obstacles as reserved space. Clearances are your choices; there is no universal allowance. Compare a regular single layer, then check the route by hand.
What the calculation does
Usable width = shelf width − left − right. Usable depth = shelf depth − front − back. Usable height = shelf height − top. Along each floor direction, count = floor((usable + gap) ÷ (bin + gap)). Occupied length is count × bin + (count − 1) × gap. If there are no boxes, occupied width and depth are both zero.
This compares only the checked regular grids. It does not solve mixed rotations, mixed sizes, stacking, diagonal insertion or the three-dimensional packing problem. Remaining width and depth are unused strips, not a promise that another bin can be added.
Before you buy
Check the door opening, hinges, handles, shelf lip and the space needed to lift or pull each box. Product dimensions can vary. The result is a geometry comparison, not a load, stability or safe-stacking assessment. Print the result and carry the measurements with you.
