What if you could do it on your own? You could save a ton of cash and save the children from a life low paying job. Or even worse, staying at home when they are older. You have seen the commercials on TV about the windows you want. The only thing is you do not know what size you need. How do you find out? Well read this and it tell you about vinyl replacement window measurement and you can begin the transformation of your windows.
The precise measurement for you new windows is going to be extremely important. Measure too small and your new windows will need extra work to get them to fit. Order them too large and well, let’s just say there is no recourse for ordering too large. Too large means you will send them back. More cost.
Do not let the consequences scare you. Measuring for the new windows is not as hard as it would seem. Let’s assume your old windows are the double hung variety with the sash locks. It is a typical standard old window. When calculating your windows always give WIDTH x HEIGHT.
Making the WIDTH Measurement
Now, to measure your WIDTH, take your tape measure and start at the top right corner of your window and measure to the left corner of the window. Be sure to include that 1½ inch pocket that the window slides in. Measure it to a sixteenth of an inch. Next make the same measurement at the mid point right above the window lock.
Then take the same measurement at the bottom. They all should be the same measurement. If, for some reason, the measurements are not the same, take the smallest measurement out of the three. Now subtract ¼ inch from the smallest measurement. That number will be your new window’s WIDTH.
Making the HEIGHT Measurement
Now it is time for the HEIGHT of the window. Measuring the HEIGHT is a bit more difficult than WIDTH.
If your window sill slopes downward for drainage, measure from the HIGHEST point of the sill. You want to measure from the top right corner to the bottom right corner. Put your tape at the top where the upper sash closes.
If the bottom has a 5/8 of an inch high inside wood sill piece to prevent water from coming inside, you need to raise the bottom sash and run the tape past the 5/8″ inch sill and down to the high point of the sloped sill. Do this in the middle and on the left. Once again, take the smallest measurement, but this time deduct 3/16″ of an inch. This is the HEIGHT.
Making the DEPTH measurement
The DEPTH measurement means from the point outside where the top sash rests against the outside wood stop to the point inside where the inside sash rests against the inside stop. This is the depth of the pocket where both sashes slide.
This measurement should be between 3 1/4″- 3 1/2″. This measurement is important to find this dimension is because not all replacement windows have a 3 1/4″ depth frame. The replacement window should fit right into the existing pocket of the wood frame.
If you purchase a window with a 2 5/8″ frame depth, you’re going to have approximately 3/4″ to fill. That means buying new wood stops for the inside of the house that are 3/4″ wider than the existing stops. Get the 3 1/4″ frames and save yourself a lot of extra work.
These measurements are usually done by the contractor or estimate giver on your window replacement project. If you have these numbers handy, you might show them that hey you know what you are doing, don’t try and gouge me on the price.
