Fascia Board Calculator for the Edge, Not the Soffit Area
A fascia board calculator on this page adds eave length to rake length. Eighty feet plus 40 feet is 120 linear feet. Boards stay blank until you type the stick you will buy.

Eave, rake, and an optional pitch if the rake was taped flat.
Eighty feet of eave and 40 feet of rake are the numbers in the boxes. They are not a house. Rise, waste, and stock length stay blank until you type them.
This fascia board calculator reads 120.000 linear feet. No board count, because no stock length was typed.

This Fascia Board Calculator Is Not a Soffit Count
Soffit is the underside, an area. Fascia is the face board on the outer edge, a length. The soffit calculator multiplies eave length by overhang depth and says fascia length is the eave you already measured. This page is that missing length, plus the rake, and it stops at linear feet until you type a board.
A hip roof often has eaves and no rake fascia. Type zero for the rake. A gable has both. Measure the edges that will actually get a board. An opening you are skipping should come off the number before you type it. This page does not guess returns.
Worked edge
Eave 80 feet. Rake 40 feet, already the sloped length, so rise stays blank. The result is 120 linear feet. Type a waste percent if you want offcuts included. Type the stock length if you want a board count. Neither default was fetched, so neither is filled in.
| Line | Input | Example |
|---|---|---|
| Eave | feet of horizontal edge | 80 |
| Rake | feet, slope or flat | 40 |
| Rise per 12 | only if the rake is flat | blank |
| Linear feet | eave + rake | 120 |
| Boards | only if stock length is typed | blank |
How should you measure the runs?
- Tape every eave that gets a board, and add those runs before you type the eave.
- Tape the rake along the slope when you can, and leave rise blank.
- If the rake number is a flat projection, type the rise per 12 so the slope factor applies once.
- Subtract edges that will not get fascia before you type them.
- Type the stock length from the yard, not a length this page invents.
- No price on this page.
What the Fascia Board Calculator Leaves Out
Public fascia calculators also offer a corner allowance and a price per foot. Those were not fetched as a standard, so they are not defaults here. If a corner eats a foot, add that foot to the eave or the rake yourself.
Rafter length, which is the sloped common rafter and not the fascia run, is the rafter calculator. Roof area in squares is the roofing squares calculator. Sheathing sheets are the plywood calculator. None of those is a fascia stick count.
The slope factor used when you type a rise is the same geometry as a roof pitch multiplier: the square root of one plus (rise over 12) squared. It is applied only to the rake box, and only when that box is a flat measurement. Demand for this URL is from the public result list. Ahrefs was not refreshed.
Frequently Asked Questions
How does the fascia board calculator get linear feet?
It adds the eave length you type to the rake length you type. Eighty feet of eave and 40 feet of rake are 120 linear feet. Boards appear only after you type a stock length.
What if the rake was measured flat, not along the slope?
Type the rise per 12 inches of run. The fascia board calculator multiplies that rake by the square root of 1 plus (rise divided by 12) squared. Leave the rise blank if you already taped the slope.
Does this page include soffit panels?
No. Soffit is an area, eave length times overhang depth, on the soffit calculator. Fascia is the linear edge. This page does not count J-channel or panels.
Why is there no board price on this page?
No board price was fetched. Stock length and waste are inputs. The count is whole boards only after you type the length the yard sells.
