beam rafter overhang

[pgtips]

Hello,

Sorry if this is a daft Q. Building a garage. For the rafter overhang on outer wall I read 12" is good for a garage. I want to keep everything as off the shelf as possible without never ending trims and cuts.

So my Q, is that measured a simple 12" out from the outer wall edge?. I.e cutting my plumb line 12" from the wall?

I ask because there's 2 measurable edges, base and/or longest side..
(generic cut image from the internet)

and then add to this gutter and clips I'm seeing this sticking out 18" on a 12" overhang. Is that right ?

I'm going to do 12" overhang on the other ends, the rake.

many thanks
PG

I normally trim my rafters afterwards, rather than trying to buy a specific length of timber.

There is no "good" size for the overhang and contrary to common talk, bigger is not always better.

12" is massive and may not look right and will lower the soffit line and coukd look wrong too relative to opening head heights.

Soffit width and fascia depth are related and can alter the whole appearance.

Also consider the soffit board material and standard component widths.
