Estimating Quantities for
Black Post & Rail Style - Part 3 || Next Part
To figure rails, let's start with the longest side,
235'. Since the black post & rail style uses 8' rails, divide 235' by 8' rails. As
illustrated in red, that is 29.375. Round to next highest (never round down). We have
sections 8' long. Multiply that by the number of rails to be used according to
the style you have chosen; 3 for three rail and 4 for four rail.
In our example, we are building a 3 Rail Fence. So 3 times
90 eight foot long rails. Granted there is some waste. In fact the last section actually
is only 3' long. The remaining rails after being cut are waste, unless we can use it elsewhere on the job.
The fact of the matter is that we can use it here. So
we will save them. To calculate the rest of the rails, repeat the process for each side
and attempt to use the leftovers from previous sides.
It pays to make the sides even multiples
of 8' to avoid waste. That is not always possible. Reconfigure your fence to
The vinyl is easy to work with so we commonly order all
8' rails. In your case you may not be able to use all the extra
material when you are done. Figure it close and order the extra few pieces you may need
later. Most items can be shipped economically by UPS except the 8' rails. Make certain
your initial order includes all of those.
