a 100 ft × 6 ft run stained on both faces, two coats at 200 ft²/gal with 10% waste rounds to 14 gallons. In metric, face area is 111.48 m².

FEN-STAIN-001v1.0.0Project inputs
Enter your measurements. Switching units converts the same project, including coverage and unit rates. Package yields keep the unit printed beside each field.
Refine measurements and rates at any time. Your current values are included in the material-list PDF.
Planning estimate, not engineering advice. Confirm site measurements and product specifications. Calculation limits.
Fence length times height times faces stained, times coats, divided by labelled coverage after a visible waste factor, rounded up to whole gallons.
- Measure the run and the face height, not the post length in the ground.
- Choose one face or both. Rails and posts eat extra — that is the waste field.
- Replace coverage with the stain can in your hand. Deck stain is a different calculator.
Add your project costs
Enter supplier prices and any labour, equipment or delivery costs. Pick a currency — badges, inputs, and totals follow.
Costs use the post, panel, fabric, stain or cap rate you type. Construclytic does not fetch fence-yard prices. Gates and slope racks stay extras. For GCC projects, select QAR, AED, SAR, KWD, OMR or BHD and enter local supplier rates.

Fence length times height times faces stained, times coats, divided by labelled coverage after a visible waste factor, rounded up to whole gallons.
FEN-STAIN-001 is gallons of fence stain, not a picket count. Run × height × faces × coats ÷ labelled coverage, with waste visible so posts and rails are not hidden inside a coverage fudge. Deck stain is a different calculator with a different product.
Worked example. Example: a 100 ft × 6 ft run stained on both faces, two coats at 200 ft²/gal with 10% waste rounds to 14 gallons.

This separate example uses the calculator's starting values in imperial units. It stays unchanged when you edit the tool above. Example rates, yields and dimensions are assumptions, not recommendations for your project.
| Input | Example value |
|---|---|
| Fence length | 100 ft |
| Fence height | 6 ft |
| Faces stained | Both faces |
| Number of coats | 2 count |
| Coverage per gallon | 200 ft² / US gal |
| Waste factor | 10 % |
Example result: Gallons of stain — 14 gal.
length × height × faces × coats × (1 + waste) ÷ coverage
Use the labelled units above when reproducing this example. To work in metric, switch the calculator to Metric; applicable measurements are converted, while product-specific units remain labelled.
- 1. Measure the run and the face height, not the post length in the ground.
- 2. Choose one face or both. Rails and posts eat extra — that is the waste field.
- 3. Replace coverage with the stain can in your hand. Deck stain is a different calculator.
Field notes that change the number
- Measure the finished face height, not the post length in the ground.
- Both faces is the default. Street-only staining is the one-face option.
- Replace coverage with the stain can in your hand. Semi-transparent and solid hide do not share a number.
Common mistakes
- Using the wood-fence picket count as a gallon line.
- Folding primer or a second colour into the same can count.
- Treating this as a coating specification or a colour match.
In Qatar and the wider GCC, stain and sealer coverage still follows the can. Switch currency to QAR; do not invent a Gulf coverage.

Questions
Questions about fence stain
Does this include the picket count?
No. Pickets and privacy boards have their own tools. This page is gallons of stain.
One side or both?
Both faces is the default. Street-only staining is the one-face option.
What is the formula ID?
This fence stain calculator publishes formula FEN-STAIN-001, version 1.0.0. The ID stays on the result and on the estimate line.
