4th border 3"
5th border 3"
All borders equal 15" X2 (top and bottom or two sides) equals 30".
Center block is 63"-30"=33" for width and 82"-30"=52" for length.
If you want different width borders just fill in your numbers and do the math. Don't forget to add seam allowance before cutting (ask me how I know, lol)
Good luck
You have to add seam allowances when you cut them. Now that is where most people make an error And if you have a longarmer quilt it it needs to be wider to accommodate putting it on the machine
