How to Measure Glass for Wooden Window in 5 Easy Steps

Step 2: Measure the Width

The next step is to measure the width of the window frame. To do so, start by measuring the inside edges of the window’s frame from one side to the other.

Step 3: Measure the Height

Next, measure the height of the window frame from top to bottom. When doing this, make sure to measure from both inside and outside edges of the frame. This will give you an accurate measurement of the overall height.

Step 4: Calculate the Area

To calculate the area of glass required for your window, multiply the measurements you took in steps 2 and 3. The result will be an approximate square footage of glass that is needed to fill the window frame.

Step 5: Get a Quote

Once you have the measurements and know how much glass is needed, you can get a quote from your local glass supplier. Make sure to provide them with accurate measurements and ask for different types of glass that are available so that you can make an informed decision.
