Closet Space Calculator

Plan a closet — from its size, the rod levels and the shelves — in hanging length, shelf area, storage volume and garment capacity.

A closet is hanging length, shelf area and volume — and the garments are the hanging length divided by a hanger. This calculator is that plan, from three measurements.

Enter the closet; the storage follows.

How many hanging rods, one above the other — 1 for long clothes, 2 for double-hang.
How many shelves the closet has.

Formula

hanging length = closet width × rod levels shelf area = width × depth × shelf count storage volume = width × depth × height garments = floor(hanging length ÷ 0.05 m) — about 5 cm per hanger, a documented planning figure.

All lengths are converted to a single unit before the calculation: 1 ft = 0.3048 m, 1 in = 25.4 mm, 1 ft² = 0.09290304 m², 1 yd² = 9 ft². Material quantities are rounded up — you cannot buy part of a tile, plank or bag.

How to use this calculator

  1. Enter the closet width, depth and height.
  2. Enter the rod levels and the shelves.
  3. Read the hanging length, the shelf area, the storage volume and the garment capacity.

Worked example

Closet2.4 m × 0.6 m × 2.4 m, 2 rod levels, 3 shelves
Hanging length2.4 × 2 = 4.8 m
Shelf area2.4 × 0.6 × 3 = 4.32 m²
Storage volume2.4 × 0.6 × 2.4 = 3.46 m³
Garmentsfloor(4.8 ÷ 0.05) = 96 garments

Check it by hand: every step above uses the formula in the box. If your numbers match the example inputs but the calculator gives a different answer, please report it via the contact page.

Frequently asked questions

How many garments fit on a hanging rod?

About one every 5 cm — so a 2.4 m rod holds about 48 garments, and two levels hold about 96. Thick coats need more room; thin shirts need less.

What is double-hang?

Two rods, one above the other — the top for shirts and jackets, the bottom for trousers and skirts. It roughly doubles the hanging length in the same closet.

How deep should a closet be?

About 600 mm — enough for a hanger (about 450 mm) plus clearance. Shallower closets crush clothes against the door.

Is this a substitute for building design?

No. This is a space-planning calculation. Structural requirements and building-code compliance vary by location — see the safety notice.
