Fence and Deck Paint Calculator

How much paint for a fence and deck? Enter the fence length and height and the deck area, and get gallons and cost as a range — rough, weathered wood sits at the thirsty end.

Leave 0 if there is no fence.

Leave 0 if there is no deck. Length × width of the deck floor.

Paint for 1,200 sq ft of fence + 200 sq ft of deck

7.00–9.50 gal — 26.5–36.0 L

$175–$521 — estimated paint cost

Total paintable area: 1,400 sq ft (130.1 sq m). Coverage: 300–400 sq ft/gal — weathered, rough-sawn wood drinks paint and sits at the low end; smooth, previously painted boards sit at the high end. A fence sprayer wastes more paint than a brush, so buy toward the high end if you are spraying.

Estimate — check the can label and current shelf price. Coverage varies by brand, finish and surface, and prices vary by store and region. The range above is a planning figure, not a quote.

Formula used: Fence area = length × height × sides. Total area = fence area + deck area. Gallons = total area × coats ÷ coverage, rounded up to the nearest quart.

How this estimate works: Fence area is length times height times the number of sides painted, and deck area is added on top. The sum is multiplied by coats and divided by the coverage range for wood — the range is wide because old, rough wood can take twice as much paint as smooth, sealed boards.
