Because the length of the run is what varies most between houses, so the linear foot is the unit that lets you compare quotes fairly. A price for the whole job hides how much gutter you are actually getting. A price per foot, on a known length, shows what the work really costs and where a quote is off.
Gutter Answers connects you with licensed local companies. We are not a contractor and do not perform the work ourselves.

You measure the horizontal roof edges, not the slopes, since gutter follows the eaves.
For what the resulting rate should include, see the full cost picture.
Once you have the length, the arithmetic is simple.
| Step | Example |
|---|---|
| Linear feet times material rate | 170 ft times $10 is $1,700 |
| Add downspouts | 4 downspouts, roughly $400 to $800 |
| Add corners and outlets | A modest allowance |
| Add fascia repair if needed | The unknown until the gutter is off |
The total is a working figure, not a bid.
It leaves out the things that cannot be measured from the ground, chiefly the fascia and the true access. Those are exactly where two honest quotes diverge, so treat the figure as a check rather than an answer.
To see the install the figure pays for, read what the parts are called.
A typical single story home has roughly 150 to 200 linear feet. Measure each eave that carries a gutter and add them for your own total.
No. Gutter follows the horizontal eaves, so you measure those. The sloping rake edges take no gutter and are left out of the length.
Multiply your linear feet by a per foot material rate, then add downspouts, corners and any fascia repair for a working total.
Because length varies most between houses. A per foot rate on a known length lets you compare quotes on the actual work rather than a lump sum.
