Doors FAQs

What is the standard door size?

The standard door is 80 inches tall, 36 inches wide, and 1 ⅜ inch thick. Exterior doors are the same height and width but are 1 ¾ inch thick instead.

How to measure the size of a door?

To measure the size door that you need, start with the width of the door frame. Next, measure the height of the door frame. Afterward, measure the thickness of the door to get the full dimensions.

How do you paint a door?

To paint a door, you can remove it from the hinges or paint it standing up. The first step is to prime the doors. Then, you can paint the door.

Consider the time of year when you are painting because you don’t want the temperature to be too hot or too cold. When you purchase a door from Window World, you can choose from a wide selection of door colors.

Can a screen door be put on any door?

While screens may not be essential for all door styles, our patio door offerings are sold with screens, providing enhanced ventilation, protection, and privacy.

Does Window World offer screens?

To enhance air circulation, privacy, and protection, screens are included with our patio door styles. Please note that we do not sell door screens separately for our other door options. If you have questions regarding our door or window products, contact a Window World representative today!

Window World did two replacement casement windows and one patio door. They came on time, were professional and completed their work in a timely manner. Used drop cloths on floors and furniture.
