What length rafters?

[Stuart J]

If a shed is 5.486m to the eaves, 12.288m wide, with a roof pitch of 15 degrees....how long are the rafters?

You'll need purlins for that span

Will depend how wide your columns are if that width is to the outside

As said above. You need to calculate distance between your posts and don’t forget to allow for 4x plates on your rafter lengths

@spark plug where can i find that calculator, looks ideal

overall span divide by 2 take 1 post of and thickness of 2 endplates then divide this answer by 15cos and you will have your answer use your scientific calculator on your phone

Put the shed up then measure it

it’s an app call trig solver, I’ve just looked on the App Store and can’t see that app at the minute but there’s loads of others there doing the same thing, it’s a very handy little tool.

That’s a seriously steep roof.
