Make every square foot count.
Storage & Space-Saving Calculators
Free tools for the numbers behind an organised home — storage volume, shelf and closet planning, room layout and fit, media capacity, moving boxes, and under-bed storage.
Storage Volume & Capacity Calculator
Turn a box or shelf's length, width, and height into cubic feet, litres, and gallons — or work out how many bins actually fit a cupboard, closet, or shelf
Shelf & Closet Rod Planner
Plan open shelving — items per shelf, shelves up a wall, and the brackets you need — or estimate how many garments a closet rod can hang
Room Layout & Furniture Fit Calculator
See how much free floor a layout leaves and what share stays walkable, and check whether a sofa, bed, or cabinet will fit through a door or gap
Bookshelf & Media Capacity Calculator
Estimate how many books, DVDs, records, or discs a shelf unit holds by dividing its total linear shelf space by the average spine thickness
Moving Box & Bin Estimator
Get a box shopping list for a move — small, medium, and large — from the rooms in your home or from a volume of belongings in cubic feet
Under-Bed & Drawer Volume Calculator
Turn an under-bed clearance or a drawer's inside dimensions into usable volume in cubic feet and litres, and how many flat bins tile the footprint
Storage & Small-Space Museum
Step into an illustrated museum of how homes hold their stuff — the chests, wardrobes, and cabinets that store it, the shelving and systems that stack it, the boxes, baskets, and containers that sort it, and the fold-away beds and built-ins that make small spaces work, each in its own gallery. Get to know the furniture and ideas behind a tidy little home.

How Much Storage a Small Bedroom Actually Has
Run all six calculators over one 12 × 10 foot room and the answer is about 43 cubic feet of storage, 17.5 of it under the bed. Most of it is already there and unused.
Litres, Inches, and the Bin That Turned Out to Be the Wrong Size
Bins are sold in litres and spaces are measured in inches. A 16 × 11 × 6 inch bin is 17.3 litres — and knowing that one cubic foot is about 28 litres settles most of the confusion for good.
One More Shelf Costs Three More Brackets, and Two Inches of Spacing Costs a Whole Shelf
Dropping shelf spacing from 16 to 12 inches on the same wall takes it from 20 items to 28. The wall did not change; the decision about what goes on it did.
The Bed Is Nearly a Third of the Floor Before Anything Else Goes In
A queen bed takes 28% of a 12 × 10 bedroom. Add a wardrobe and a desk and 58.9% is left — which is not the same as being walkable.
Why You Need Twice as Many Small Boxes as Medium Ones
A bedroom's 45 cubic feet comes out as 12 small boxes, 6 medium and 2 large. Small boxes carry 40% of the volume and are 60% of the count — and that is the correct answer, not a quirk.
The Kitchen Needs More Boxes Than the Bedroom
A kitchen is 55 cubic feet of boxable things — 26 boxes — against a bedroom's 20. It is the smallest room in most homes and the one that packs largest.
