Fence Paint Calculator
Calculate fence-paint quantity from the area of panels or boards, coat count and the paint's coverage rate.
Calculate fence-paint quantity from the area of panels or boards, coat count and the paint's coverage rate. This estimate is most useful when the inputs reflect the job as it will actually be built, fitted or coated. Give particular attention to coverage rate, coats and absorbency. A fence measurement can be understated if only the face area is counted. Decide whether both sides, edges, posts and gravel-board details are being painted.
What you need to enter
The Fence Paint Calculator uses the following project information to calculate the result.
- Area
- Number of coats
- Coverage per unit
- Extra allowance (%)

How the Fence Paint Calculator works
The Fence Paint Calculator uses the measured fence surface area, number of coats and the paint's real coverage rate to calculate coating volume before the chosen allowance is applied. Decide whether one or both faces, posts and rails are included in the measured area, and allow for the higher absorption of rough-sawn timber where relevant. The final quantity should be matched to purchasable container sizes.
Fence Paint Calculator worked example
Fence Paint Calculator example: Six 1.8 m × 1.8 m panels painted on both faces provide 38.88 m² of coating area. At two coats and 8 m²/L coverage, the base requirement is 9.72 L; adding 10% gives about 10.7 L. Posts, rails and rough-sawn texture can add further demand. Before relying on that figure, check coverage rate, coats and absorbency; the final decision should also follow the actual product or project specification.
Important calculation assumptions
For paint for fence panels, boards and other timber fencing, a fence measurement can be understated if only the face area is counted. Decide whether both sides, edges, posts and gravel-board details are being painted.
Frequently asked questions
Which measurements should I confirm for the Fence Paint Calculator?
Measure the surface area that will actually be coated, then enter the number of coats and the coverage figure printed for the exact product. On this page, the measurements are used specifically for paint for fence panels, boards and other timber fencing.
What should I know about coverage rate, coats and absorbency before using the Fence Paint Calculator?
Do not chase extra decimal precision in the Fence Paint Calculator until you have realistic values for coverage rate, coats and absorbency. A fence measurement can be understated if only the face area is counted. Decide whether both sides, edges, posts and gravel-board details are being painted.
What should I check before buying from the Fence Paint Calculator result?
Once the Fence Paint Calculator has produced a result, round up to whole tins and confirm whether the calculation includes both faces, edges and posts. Keep extra product if future touch-ups need the same colour batch.
