01 / MEASUREMeasure the space you actually have.
Measure the inside width, height and depth of each shelf opening, not the outside furniture dimensions. Check hinges, back panels and shelf sag. In My Real Shelf, enter the smallest measured dimensions and add a clearance allowance to each box.
02 / ROTATEVolume is only half the story.
A shelf can have plenty of empty volume and still reject a wide box. Rotate a box to change its front footprint, while keeping its depth within the shelf. Gap Vision marks free front area; the ruler reports the widest floor-level opening. Neither guarantees that every box will fit.
03 / PROTECTMake game night easier.
Keep frequently played games on top or within easy reach. Do not stack on fragile lids. This planner rejects unsupported placements and stacking on boxes marked fragile, but it does not calculate real weight limits. Follow your furniture manufacturer’s load rating.
