Example: 16x20=6' (around the whole frame of course, not UI) + 1" moulding gives you 80" divide by 12"= 6.66 ft. What if anything do you add for waste? If you order chop do you know what your vendor adds? I haven't looked into this in years but so far the two vendors I've looked at both seem to add .3 ft (after first rounding to the nearest 1/10)
 
I think it's a case of swings and roundabouts and it all evens out eventually. I do a regular trade order for biggish frames. They are about 14ft around the outside. In practice, I can only get two long rails or two short rails out of 10ft length. The remaining 6ft is usuable, but I haven't really got a use for it. I use a bit occaisionally on smaller jobs, but I have to regard the offcuts as waste. Sometimes you get a bad section in a length that I can't cut around and can only get one rail out of a 10ft length. So I have to add extra for this. Even if I add 10%, it means I am consuming 22ft per frame.

Then again you get other dream jobs that use a moulding that is not prone to twisting or defects and the rail lengths fit nicely into a length meaning minimal wastage.

Sheet materials are worse. If a sheet of matboard is 40" long and you have to cut mats that are 21" wide - one sheet = one mat. One inch smaller and you cut your matboard costs in half.
 
I noticed that the software I am now using seemed to be adding on to the footage you'd get just by doing the straight math. I assumed it was a "waste" setting that I could adjust. Turns out that this is not the case. I use quite a few vendors & order mostly by chop. All my pricing is based from chop anyway. It turns out that each vendor may (or may not) be charging a "waste" allowance. Full Calc has obtained this info from the vendors & factored it in for each vendor.
 
It depends on the vendor

I have found that every vendor has a slightly different method for charging for chops. Some round up to the next foot; some up to the next 1/2 foot, and some to the next 1/3 foot.

If you order straight cuts, it is the chop formula, but they generally add 1 inch to each side [4" more total] for shipping, but the actual charged price can be up to 1 foot more than what they send you. I have learned to calculate the chop dimensions, add 1 foot, and round up to the next foot and I'm covered.

I even have one vendor that charges different based on which location ships; one rounds up to the next 1/2 foot, and another up to the next 1 foot.
 
I've always been vaguely aware of vendors doing this but I think I'll try & track this a little more closely for a while. It's nice of my software program to get this info from the vendors & factor it in but I was a little taken aback at the extra footage on small frames.
