Quick answer
Estimate paint or stain area for a fence by length, height, number of coated sides, coats and product coverage. Use the working RenoMetric calculator below for the actual estimate, then use this page to check assumptions, package rounding and project-specific considerations.

Formula
Worked planning example
A 100 ft fence that is 6 ft high has 600 ft² on one side or 1,200 ft² for both sides before coats.
Common uses
- Wood fences
- Privacy fences
- Fence stain
- Exterior maintenance
How to get a better estimate
Measure the actual project rather than relying on listing dimensions. For irregular spaces, split the surface into simple measurable sections and add the results. Use the exact product label for package coverage, yield, density or square-foot coverage whenever it is available.
Keep waste and package rounding as separate steps. Waste covers cuts, breakage, pattern matching and unavoidable offcuts. Package rounding reflects the fact that many materials are sold only in complete bags, boxes, bundles or cans.
Before you buy: this page is a planning guide, not a contractor quotation or structural design. Verify final quantities with the product manufacturer, supplier or installer when project conditions could materially change the result.
Fence Paint Calculator FAQ
Should both sides be counted?
Yes if both sides will be coated. Multiply the face area by two before applying coat count.
Do gaps reduce the area?
They can, but posts, rails and edges add surface area back. For planning, use a conservative adjustment rather than assuming every gap is a full saving.
Can I use this for stain?
Yes for area planning, but use the stain manufacturer’s coverage rate because penetrating stains can differ greatly from paint.
