Closet / Shelving Calculator
Work out exactly how much shelving, how many brackets, and how much hanging rod a closet needs from its wall runs and tier count. Add your own prices for a full cost estimate — nothing here uses a stale national average.
How this calculator works
Total shelving footage multiplies your wall runs by how many tiers you're stacking, since each tier repeats the full run. Brackets are worked out from that combined footage, with one extra bracket added per tier for the row's end support that a simple division misses:
total_shelf_linear_ft = sum(wall_length) × tiers brackets_needed = ceil(total_shelf_linear_ft × 12 / bracket_spacing_in) + tiers rod_length = hanging_section_length
The hanging rod section is measured and priced separately from the shelf-only wall runs, since it's usually a different length of the closet — a reach-in closet, for instance, often has a single rod wall and no shelving wall at all.
Worked example
A walk-in closet with 6 ft, 4 ft and 3 ft shelving walls, 2 tiers, 16 in bracket spacing, and a separate 4 ft hanging rod section:
- Total shelving: (6 + 4 + 3) × 2 = 26 linear ft.
- Brackets: ceil(26 × 12 ÷ 16) + 2 = 20 + 2 = 22 brackets.
- Rod: 4 ft, unchanged.
At $8 per linear ft of shelving, $3.50 per bracket, and $6 per linear ft of rod, that example totals 26 × $8 + 22 × $3.50 + 4 × $6 = $309.
Measuring your closet
- Wall runs — one entry per wall that gets shelving; skip walls that only get a hanging rod.
- Tiers — count of stacked shelf rows, not counting a rod-mounted shelf if you're tracking that separately.
- Bracket spacing — 16 in is a common default; check your shelving product's load rating for the max spacing it supports.
- Rod section — measure the wall length that gets a hanging rod, separate from shelf-only walls.
How much does closet shelving cost?
Rather than quoting a national average that's stale the day it's published, this calculator prices the job from what you actually enter. Give a shelving price per linear foot, a price per bracket, and a rod price — either per linear foot or per fixed-length kit — and each is itemized and totaled. The estimate doesn't include drawer units, baskets, or installation labor.
Frequently asked questions
What are standard shelf tier heights and spacing?
About 12 to 16 inches between tiers is typical for folded clothing and bins. A shelf-and-rod combo commonly sets the shelf around 66 to 84 inches up, with a multi-tier stack's top shelf usually capped around 84 inches for reach.
How much hanging rod space does each garment type need?
Roughly 1 to 1.5 inches per shirt or folded pant, and 2 to 3 inches for bulkier items like dresses, coats and suits. Counting garments by category is a good cross-check against your rod length input.
Wire vs solid wood shelving — what are the tradeoffs?
Wire shelving is cheap, easy to install, and ventilates well, but can crimp delicate items and needs more brackets over long spans. Solid wood is sturdier and better finished, but ventilates less and costs more per foot.
How does a reach-in closet layout differ from a walk-in?
A reach-in closet is typically one wall or a shallow U-shape with one rod and one shelf above. A walk-in has multiple walls and floor space, so it can dedicate different walls to shelving, hanging, and drawers separately.
