Basic door measurements are required to get a price together for your project. The easiest way to measure your doors yourself is to measure from brick to brick, in width and height. A quick sketch of each door with the accompanying measurements will help speed up the quoting process substantially. Remember to include any sidelite or transom options. It is very important to have the installing contractor verify with a final measure before ordering. This will ensure that all their preferences are met, ensuring a smooth installation.
