Closet & Shelf Capacity Planner
Enter a closet or wall’s width and the height you want to shelve, pick a shelf spacing, and see how many shelves fit, the shelf run you gain, and — with a rod — how many garments it holds.
Capacity of this space
Shelf count is the number of full spacings that fit in the height. Leave a little extra headroom on the top shelf so you can actually slide things in and out.
Design the space before you drill
The difference between a closet that swallows your things and one that fights you is usually shelf spacing. Pack the shelves too close and tall items don’t fit; space them too far apart and you waste the air above every stack. Working out the shelf count and spacing on paper first — before you cut a single board or drill a bracket — is the cheapest way to get a layout that actually works.
Use the numbers to plan a double-hang section for shirts and trousers, a run of shelves for folded clothes and bins, and a top shelf for the things you reach for twice a year.
Frequently Asked Questions
How many shelves fit in my closet?
Divide the vertical space you want to fill by the spacing you'll leave between shelves. This planner does that for you — at 12-inch spacing a 72-inch run gives six shelves — and multiplies by the width to tell you the total linear feet of shelf you end up with.
What shelf spacing should I use?
It depends on what goes on them. About 12 inches suits folded clothes, books, and small bins; 16 to 18 inches works for larger storage boxes and stacked items; kitchen and pantry shelves are often 14 to 16 inches. Leave a little extra on the top shelf so you can actually slide things in and out.
How many clothes fit on a hanging rod?
It comes down to how much rail width each garment takes. Shirts on slim hangers need about an inch each, everyday clothes on standard hangers around two inches, and bulky coats closer to three. The planner divides the rod length by your per-garment width to estimate capacity — tick the hanging-rod option to include it.
Does 'linear feet of shelf' mean storage capacity?
It's the best single measure of a shelving layout: the total length of usable shelf surface you'll have. Two narrow shelves and one wide one can give the same linear feet; what you store determines whether you want more short shelves or fewer tall ones.
Can I use this for a pantry or garage, not just a closet?
Yes. Any wall or reach-in space works the same way — enter the width and the height you'll fill with shelving. For a garage or pantry you'll usually skip the hanging rod and use wider shelf spacing for bins and boxes.
A planning estimate. Real capacity depends on shelf thickness, bracket type, and what you store — leave headroom on each shelf and check that fixings suit your wall and load.
