What problem this solves
The standard “walk-in closet needs 2 m × 2 m” rule assumes a generic wardrobe. Real closets fail when the actual mix doesn’t match the assumption: a person with 60 shirts but only 4 dresses needs almost no long-hang space; a person with 20 dresses and only 10 shirts needs the opposite. The National Kitchen & Bath Association publishes a per-category guideline; this calculator applies it to your actual counts.
The output is also a sanity check on “do I really need to expand the closet?” If the calculator says you need 3.5 m of wall but the existing closet is 4 m, you’re fine. If the existing closet is 2.5 m and you need 3.5 m, you have an honest conversation to have with the client about paring down, expanding, or accepting lower density.
Who it’s for
- Custom closet designers sizing a build before quoting
- Bedroom designers deciding between reach-in and walk-in
- Homeowners planning a master suite renovation
- Real-estate stagers figuring out how much a small closet can hold
Why per-category beats rules of thumb
A rule like “allow 1 linear foot per hanging garment” works only if everyone hangs everything. It overestimates for someone with 30 T-shirts (most of which should be folded) and underestimates for someone with 20 winter coats (each coat needs 4 cm of width plus a higher rail). Per-category math gives a more honest answer and a more honest layout — a closet with 4 m of short hang and 0 m of long hang for someone who doesn’t own long garments is a closet that wastes 1 m of long-hang rod.
Limitations
- Densities assume standard hangers (0.5 cm thick) — velvet hangers are 0.2 cm and can fit 2.5× more.
- Seasonal items (winter coats in summer, swimwear in winter) are counted as if present year-round.
- Drawers default to 60 cm wide; deeper 80 cm drawers hold more but need a larger closet.
- Shoes assumed stored on a rack — a shoe wall uses 0.5 m² per 20 pairs.
- Shared closet divides linearly; in reality partners’ wardrobes peak in different seasons.
Practical layout rules
Section a closet top-to-bottom: 170–200 cm for long hang, 90–110 cm for short hang, then shelves above (folded items) and drawers below. Aim for the long-hang section to face the entrance so you can see all long garments at a glance. Allow 60 cm of clearance in front of any hanging rod for you to pull a hanger sideways. Allow 90 cm in front of a drawer bank so it can be opened fully.
