Closet Organizer Calculator
Plan your closet from width, depth, and height.
Returns shelf count, rod lengths, and a zone layout for double-hang, long-hang, and shoe storage areas.
A well-planned closet organizer maximizes every cubic inch of storage. The planning process involves measuring the space, deciding on zones (hanging, shelving, drawers), and calculating material quantities before purchase.
Key formulas:
Total Hanging Length = Σ(Item Category Count × Space per Item) Shelf Area = Shelf Width × Shelf Depth Number of Shelves = Closet Height ÷ Shelf Spacing Linear Feet of Shelving = Number of Shelves × Shelf Width Estimated Cost = Linear Feet × Cost per Linear Foot
What each variable means:
- Item Category Count — count shirts, pants, dresses, etc. in your wardrobe before designing.
- Space per Item (hanging width): shirts ~2 inches each | pants (folded) ~2.5 inches | dresses ~3 inches | jackets ~3–4 inches.
- Shelf Spacing — standard: 12–14 inches for folded clothes; 16–18 inches for shoes; 10–12 inches for accessories.
- Cost per Linear Foot — melamine: $15–$30 | wood: $20–$40 | professional custom: $100–$300.
Standard closet zones and heights:
- Double hanging (shirts over shirts): Upper rod at 81–84 inches; lower rod at 40–42 inches; 40 inches of clearance needed per section.
- Long hanging (dresses, coats): 65–70 inches of clearance needed.
- Shelves: Typically 12–16 inches deep; 8–14 inches between shelves.
Worked example: Reach-in closet: 6 ft wide × 8 ft tall × 24 inches deep. Design: 3 ft double hang (left) + 3 ft shelving (right, 6 shelves).
Hanging rod = 3 ft; serves ~18 shirts on upper + 18 shirts on lower. Shelves = 6 × 3 ft = 18 linear feet of shelving. Material cost (melamine at $20/linear ft) = 18 × $20 = $360 materials Labor (DIY: free; pro install): ~$200–$400.
