1. Find the lowest point
Measure from the floor to the lowest frame rail, bracket, or fastener along the route the bin will travel. Check more than one point. A measurement below the mattress edge alone can miss lower hardware.
For a wheeled bin, use the overall published height including the wheels. A fabric bag should be measured when filled, rather than folded flat.
2. Divide the floor into usable zones
Measure the clear width and depth between legs and rails. Treat a center leg as the edge of a zone instead of including it in one large empty rectangle. Draw a simple top-down sketch and label each measurement.
If you can only reach from one side of the bed, a second row may become trapped behind the first. Decide whether moving the front row each time is acceptable before buying both rows.
3. Use the outside dimensions
The volume printed on the label tells you how much a bin nominally holds. It does not tell you whether the lid or handles will clear the frame. Match the exact model number and look for overall exterior length, width, and height.
The Sterilite 2260 page lists a 6-inch exterior height. The 1761 wheeled model lists 7 inches. That single inch may decide which one can use your space, even before you compare capacity.
4. Leave room to move
Avoid a zero-clearance fit. Allow an adjustable buffer for uneven flooring, flexing lids, and lifting the handle. Our checker starts with a half-inch allowance around the outside edges of the available floor area and above the box; it does not insert a half-inch gap between neighboring boxes. This is a planning choice, not a universal product standard.
Test the route with a cardboard footprint if access is awkward. Include the space outside the bed that you need to slide the bin out.
Worked example: one opening, two heights
For a hypothetical clear zone 36 inches wide, 24 inches deep and 7.25 inches high, the checker’s 0.5-inch boundary allowance leaves 35 × 23 × 6.75 inches. This is an arithmetic example, not a measured installation or fit test.
The 2260’s published 29.375 × 18 × 6-inch outer envelope fits once in that rectangle with the long side across the width. The 1761’s 34.625 × 18.75-inch footprint can also enter the rectangle, but its published 7-inch height exceeds the chosen 6.75-inch height limit. Neither result proves the loaded bin will clear a real rail, handle, carpet or center leg.
5. Choose access before volume
Daily-use shoes and spare bedding need different retrieval routines. A smaller box you can move easily may be more useful than a large box filled with mixed items. Keep each category together and label the side you can actually see.
Use the fit checker for a first-pass rectangular layout. It does not model bed legs or prove that a loaded bin can roll across your floor. Measure and check the actual product before purchase.
Put your measurements to work. Our fit checker compares a single-layer rectangular layout with adjustable clearance.
