The total length of fence to be stained.

Use the same length as the Fence Calculator.

The height of the fence.

Measure from the ground to the top of the pickets.

Staining both sides roughly doubles the area to cover.

Shared fences with a neighbor sometimes only get stained on your own side.

How this was calculated

Formula source(s)

  • Fence stain typically covers approximately 150 sq ft per gallon per coat on rough-sawn wood — lower than smooth deck boards due to picket texture; staining both sides doubles the area

Inputs used

Fence Length
98 ft
Fence Height
6 ft
Staining Both Sides?
Yes — both sides

What this calculation does not cover

  • The result is ONE COAT. How many coats the fence needs is set by the stain and the state of the wood, not by the dimensions above: a semi-transparent oil on sound wood is often a single saturating coat, a solid-color stain builds its film in two, and a bare gray fence that has never been sealed drinks the first coat so hard it barely changes color. Buy for the coats you actually intend to put on, and buy them in one go — stain from a second batch bought weeks later rarely matches the first, and the seam shows as a band down the run.
  • Length times height treats the fence as a flat panel. A board-on-board or shadowbox fence sets a second layer of boards behind the gaps, and their faces and edges are all stainable surface this rectangle never sees; a lattice top carries far more surface per foot of height than solid boards do. On either build the true area — and the stain it drinks — run well past what the elevation suggests, so measure those sections as their own job rather than folding them into the run.

Most jobs need more than one number. Add the calculators you need next and they open right here, underneath this one — your figures stay on screen and nothing is lost to a page change.

Protection this work requires

  • Stop and check first. Paint under later coats in older housing can be lead-based, and sanding or heat-stripping it produces lead dust that is especially harmful to children and to anyone pregnant. Test before you disturb it — this is a job for a tested, controlled method, not a better mask.

Tools and safety for this job

To roll and cut in two coats and strip an old coating off timber. Generic types, no brands, no prices.

  • Hardwood dust is a recognised carcinogen: extract at the tool and wear a P2/N95 respirator when cutting or sanding indoors.
  • A dust mask does nothing about solvent vapour: ventilate through, and use an organic-vapour (A1) cartridge respirator in an enclosed room.
  • Most fatal falls on small jobs are from under three metres: use a tower or a ladder tied at the top, and never work off the top two rungs.

How to calculate wood fence stain in 4 steps

  1. Fence LengthThe total length of fence to be stained.
  2. Fence HeightThe height of the fence.
  3. Staining Both Sides?Staining both sides roughly doubles the area to cover.
  4. Fence stain neededThe tool computes the fence stain needed from those figures and shows the formula, its sources, and a confidence rating alongside it.

Frequently asked questions

Should I stain both sides of a fence?
For maximum protection and even weathering, yes — the side facing the most sun and weather exposure benefits most, but both sides are exposed to moisture from the ground and rain, so both sides typically need protection over time.
Does picket spacing affect coverage?
A privacy fence with tightly spaced pickets has slightly less exposed edge area than a spaced picket fence, but the difference is generally small relative to other factors like wood texture and stain opacity.
New fence — how long should I wait before staining?
Often several weeks to a few months: pressure-treated lumber needs that long to dry out enough to properly absorb stain. Check your specific lumber and product's recommended waiting period, or do a water-bead test (if water beads up rather than soaking in, the wood isn't ready yet).
Preliminary estimate, not certified engineering. This tool produces an indicative quantity calculation for planning purposes only — it is not a certified structural analysis, a guaranteed material takeoff, or a substitute for building department approval. Always verify measurements on-site and have a licensed contractor or structural engineer review any load-bearing, code-sensitive, or safety-critical work before purchasing materials or starting construction.
