There are so many different pergola rafter tails sizes.
I have shown all the important measurements for widths from 4" to 12".
What you decide may depend on what timber sizes are available at your local timber yard.
Take "w" to mean width. The top horizontal line is 3xw =3x6 = 18".
The short vertical lines are w/4 = 6/4 = 1 1/2"
Other two lines w=6".
Draw the Outline Template first for your width.
Then draw the circle on card using the radius indicated. Cut the circle out and move the card into Position 1. Using an HB pencil draw the arc. Change to position 2 and repeat.
The diagrams work just as well with the Compasses/Setsquare and Compasses Methods too.
One customer asked:
I'm wondering why you chose the default widths? The rafters I'll be using are 2 by 8, 2 by 6 and 2 by 4. These sizes are standard. Will the default templates work for me?
In response I have now added 4" and 8" width sizes on this page. Print off version on the way soon.
I have a 10" Width that I am seeking a template for. Can you assist? Thanks, Tom
I have added the 10" size but you will have to draw it youself as I'm still working on the 10" size print off version.
My handyman instructed me to look for a template for 2 x 6 and 2 X 12 rafters. I am thinking the 6" width will work for one but I must modify it in order to get it also on the 12 inch rafter. Any help will be appreciated, and I will just have the templates printed.
I'm still getting a few requests like this for 12" and have put in the sizes here.
I am getting more requests for different size of pergola rafter tail templates from 4" to 11" in intervals of 1/4". Here is a sample of 200+ requests taken for March and April 2018.
