When to use this calculator
Estimate vertical fence pickets for a measured clear run and selected spacing. Counts a continuous clear run; posts and gates should be excluded from the run length.

PUTTING IT INTO PRACTICE
Fence Picket: a worked example
The values below are an illustrative example, not a recommendation. Replace them with measurements or assumptions that match your question.
| Input | Example value |
|---|---|
| Clear fence run (m) | 10 |
| Picket width (mm) | 90 |
| Clear gap (mm) | 10 |
| Result | 101 pickets |
- Check the input labels and enter the example values above.
- Apply the relationship: Pickets = ceiling((run×1000+gap)/(width+gap)).
- The result is 101 pickets, rounded for display.
How to interpret your result
Counts a continuous clear run; posts and gates should be excluded from the run length.
Calculate net geometric quantities first, then apply a project-specific allowance where appropriate. Coverage per bag or pack should come from the product label. Bulk density, trimming and compaction can substantially change order quantities.
Frequently asked questions
Does a geometric estimate include waste automatically?
Only when a waste or allowance input is provided. Otherwise add an appropriate allowance separately before ordering.
When is the fence picket calculator useful?
Estimate vertical fence pickets for a measured clear run and selected spacing. Counts a continuous clear run; posts and gates should be excluded from the run length.
How do I use the fence picket calculator?
Enter clear fence run (m), picket width (mm), clear gap (mm). The result updates automatically. Use the units shown beside each input; the example values illustrate the method.
Which formula does this calculator use?
Pickets = ceiling((run×1000+gap)/(width+gap)).
What should I check before using the result?
Counts a continuous clear run; posts and gates should be excluded from the run length.
How are results rounded?
Scalar numbers display up to six decimal places, with scientific notation for very large or small values. Text, fraction, date and schedule outputs use the format described on the tool. Intermediate calculations use JavaScript floating-point arithmetic. Keep sensible precision for your measurements.
