How many panels and posts does a fence run need?

Panels are fenced length divided by the panel width, rounded up on each run. Posts are panels plus gates plus one, before subtracting shared corners. With 8 ft panels, 100 ft needs 13 panels and 14 posts; the final panel is 4 ft wide. For a post-and-picket fence, Panel width is the bay spacing from your own plan. This counts that plan rather than selecting a spacing.

How do gates and corners change fence material quantities?

Gate openings come off their own run before panels and pickets are counted. Each gate adds one post in the count. A 24 ft run with a 4 ft gate leaves 20 ft of fencing, giving 3 panels, 5 posts and 60 pickets at a 4 in pitch. Two connected 24 ft runs with 8 ft panels have 6 panels and 7 posts when their corner is shared.

Can I count wood fence lumber, rails and pickets?

Picket pitch is board width plus your gap. A 24 ft run with 3.5 in pickets and a 0.5 in gap needs 72 pickets. Supplied fence rail quantities multiplies the current bay count by the rail pieces per bay in your material plan. Read posts, pickets and rails separately. It counts a single picket layer and does not design overlapping, board-on-board, shadowbox or horizontal layouts, or add fasteners.

Can I calculate supplied fence installation, removal, repair or replacement costs?

Choose the job in the supplied fence quote section. Fence installation, removal, repair and replacement multiply your affected length by your supplied rate per foot or metre, then add optional material and other quoted totals. Post installation and replacement use your positive whole post count and matching supplied rate per post. Changing between length and post-count jobs clears the quantity and rate. Use your quote's gate basis and currency. Wood, vinyl and chain link quotes can use supplied prices; the tool does not diagnose repairs or calculate chain link rolls and fittings.

Can I calculate a supplied fence pressure washing quote?

Use Supplied fence washing quote. Measure the length and height of each rectangular face included in the quote, then enter the matching supplied rate per square foot or square metre. The calculator sums those surfaces, multiplies the area by your rate and adds optional other charges. This separate subtotal needs no stain coverage or container size and adds no unmeasured faces. No washing method or local price is selected.

How much fence stain do I need?

Use Supplied fence stain coverage. Enter the length and height of each rectangular surface you want included, then the effective area one container covers for your complete selected coat schedule. The calculator sums the measured surfaces and rounds area divided by coverage up to whole containers. It adds no unmeasured faces, posts, board edges or texture. Optional container prices and application rates give a separate stain-cost subtotal; the same supplied-coverage arithmetic can be used for paint.

Can I calculate concrete bags for fence post holes?

Use Supplied post-hole concrete quantities with dimensions from a plan you already have. Enter round or rectangular hole dimensions, supplied depth, a round or square post cross-section, hole count and the manufacturer's mixed volume yielded per bag. The post occupies the full entered hole depth in this model; its displaced volume is subtracted before multiplying by hole count. The result rounds up whole bags and can price them. Round cross-sections approximate pi, and uncertain whole-bag boundaries are withheld. No post depth, product or mixing ratio is selected.

What does this fence calculator not determine?

It does not choose post depth, structural spacing, loads, fence design or code requirements. Dimensions, rail counts and prices are supplied by you. No construction method is recommended, and delivery, tax and charges you leave blank are excluded.

Which inputs are remembered?

The main runs, gates, panel width, picket dimensions and units are remembered in your browser. The four main price fields and all extra rail, job quote, washing, stain and concrete fields are not saved. The arithmetic runs locally without an account.

One row for each straight length. A fence that turns a corner is two rows, because two straight lengths are something you can check with a tape, and the post where they meet is then counted once.

Panels are whole: a run that is not a whole number of panels rounds up, and the last panel is cut to fit. Every run here divides into whole panels.
A straight run of panels stands on one more post than it has panels, because a post carries the end of one panel and the start of the next.
One run, so there is no corner post to share. Add a second run and the post where they meet is counted once.
No gate openings. Add one and its width comes out of the run it sits on, with a post added at the opening.
Pickets are counted across the fenced length on a 4 in pitch, 3.5 in of board and 0.5 in of gap, so a part panel takes only the boards it needs.
This counts material for the lengths you typed. It makes no structural, load or code recommendation.

A count of material, and nothing beyond it. Exact arithmetic on the lengths you enter. It counts material for a straight run and shares corner posts; it makes no structural, load or code recommendation. Round cross-section volumes use an approximation to pi. The panel width doubles as the post spacing, so a fence built between posts rather than from prefab panels counts the same way: the panel figure is then the bay between one post and the next. Prices are your own, in your own currency, and none of them is kept.

Common questions

How many panels and posts does a fence run need?: Panels are fenced length divided by the panel width, rounded up on each run. Posts are panels plus gates plus one, before subtracting shared corners. With 8 ft panels, 100 ft needs 13 panels and 14 posts; the final panel is 4 ft wide. For a post-and-picket fence, Panel width is the bay spacing from your own plan. This counts that plan rather than selecting a spacing.
How do gates and corners change fence material quantities?: Gate openings come off their own run before panels and pickets are counted. Each gate adds one post in the count. A 24 ft run with a 4 ft gate leaves 20 ft of fencing, giving 3 panels, 5 posts and 60 pickets at a 4 in pitch. Two connected 24 ft runs with 8 ft panels have 6 panels and 7 posts when their corner is shared.
Can I count wood fence lumber, rails and pickets?: Picket pitch is board width plus your gap. A 24 ft run with 3.5 in pickets and a 0.5 in gap needs 72 pickets. Supplied fence rail quantities multiplies the current bay count by the rail pieces per bay in your material plan. Read posts, pickets and rails separately. It counts a single picket layer and does not design overlapping, board-on-board, shadowbox or horizontal layouts, or add fasteners.
Can I calculate supplied fence installation, removal, repair or replacement costs?: Choose the job in the supplied fence quote section. Fence installation, removal, repair and replacement multiply your affected length by your supplied rate per foot or metre, then add optional material and other quoted totals. Post installation and replacement use your positive whole post count and matching supplied rate per post. Changing between length and post-count jobs clears the quantity and rate. Use your quote's gate basis and currency. Wood, vinyl and chain link quotes can use supplied prices; the tool does not diagnose repairs or calculate chain link rolls and fittings.
Can I calculate a supplied fence pressure washing quote?: Use Supplied fence washing quote. Measure the length and height of each rectangular face included in the quote, then enter the matching supplied rate per square foot or square metre. The calculator sums those surfaces, multiplies the area by your rate and adds optional other charges. This separate subtotal needs no stain coverage or container size and adds no unmeasured faces. No washing method or local price is selected.
How much fence stain do I need?: Use Supplied fence stain coverage. Enter the length and height of each rectangular surface you want included, then the effective area one container covers for your complete selected coat schedule. The calculator sums the measured surfaces and rounds area divided by coverage up to whole containers. It adds no unmeasured faces, posts, board edges or texture. Optional container prices and application rates give a separate stain-cost subtotal; the same supplied-coverage arithmetic can be used for paint.
Can I calculate concrete bags for fence post holes?: Use Supplied post-hole concrete quantities with dimensions from a plan you already have. Enter round or rectangular hole dimensions, supplied depth, a round or square post cross-section, hole count and the manufacturer's mixed volume yielded per bag. The post occupies the full entered hole depth in this model; its displaced volume is subtracted before multiplying by hole count. The result rounds up whole bags and can price them. Round cross-sections approximate pi, and uncertain whole-bag boundaries are withheld. No post depth, product or mixing ratio is selected.
What does this fence calculator not determine?: It does not choose post depth, structural spacing, loads, fence design or code requirements. Dimensions, rail counts and prices are supplied by you. No construction method is recommended, and delivery, tax and charges you leave blank are excluded.
Which inputs are remembered?: The main runs, gates, panel width, picket dimensions and units are remembered in your browser. The four main price fields and all extra rail, job quote, washing, stain and concrete fields are not saved. The arithmetic runs locally without an account.
