I don't want to sound like an ass, but that is pretty easy to figure out.

12' x 4" = 4 SF

100 SF / 4 SF = 25 pieces, throw one in for waste and you have 26 pieces!

If you do not have a construction calculator, I would suggest you to pick one up, they are great!

Hardie's installation guidelines has a great calculation tool that incorperates a 5% waste factor. Otherwise I multiply the sqf by 2 for 7 1/4 and 1.71 for 8 1/4.

Who really gets 5% waist? maybe if you had a 12x12 shed to cover and you only had to trim a couple inches of each piece for the post corner.

I'd say it atleast twice that if not 15% is the norm.

I agree. If there are gables and cheek walls involved I always go ...X1.15.
Unless you enjoy racing to the lumber yard for one more piece at 4:30pm:whistling

I just don't get how you can install a product without knowing how to calculate how much you will need.

Am I alone?

BTW- To the OP, I am sorry if I am coming off like an ass, you can ask anyone on this forum who have known me long enough to know that I am the farthest from an ass you will meet.

try posting basic questions like this on the electrical forum-they'll rip you a new you know what. Cole's presentation was more then gracious. Given the initial square footage, the height of the wall is important as you may need an extra course depending on where it falls. Do you guys adjust the overhang (1") plus or minus at times to hit the window or fascia?

no worries - I deal with asses every day

Last year my partner and I did $215,000 in Hardy Plank installs, and never once had to figure out how many planks it took.

Why?

The materials were on the job when we got there - it's crazy I know, but it happens sometimes

:w00t:
