Storage & Space-Saving Calculators
Free, practical calculators for an organised home — storage volume, shelf and closet planning, room layout and fit, media capacity, moving boxes, and under-bed storage. Educational tools, not a substitute for measuring the space yourself.
Storage Volume & Capacity Calculator
Turn a box or shelf's length × width × height into cubic feet, litres, and gallons, or work out how many bins genuinely fit inside a cupboard, closet, or shelf — grid-packed, not just by raw volume
Shelf & Closet Rod Planner
Plan open shelving — how many bins fit across a shelf, how many shelves stack up a wall, and how many brackets you need — or estimate how many garments a closet rod can hang
Room Layout & Furniture Fit Calculator
Subtract each furniture footprint from the room to see the free floor left and what share stays walkable, and check whether a piece will tilt through a doorway or gap
Bookshelf & Media Capacity Calculator
Estimate how many books, DVDs, Blu-rays, CDs, or records a shelf unit holds by dividing the total linear shelf space by the average spine thickness of each item
Moving Box & Bin Estimator
Estimate how many small, medium, and large moving boxes you'll need — from the rooms in your home or from a volume of belongings in cubic feet — for a right-sized box list
Under-Bed & Drawer Volume Calculator
Turn an under-bed clearance or a drawer's inside dimensions into usable storage volume in cubic feet and litres, with a fill factor, plus how many flat bins tile the footprint
