How to Measure Blinds for a Door

Why Doors Need Blinds

Like windows, you door also needs effective window treatment solutions for maximum benefits. Doors have wide expanse of glass which can pose a number of issues for home owners. They give rise to privacy concerns as they can reveal the interiors of the house to outsiders. They allow easy flow of heat and harsh sunlight into the room which can cause heat gain and also increase exposure to UV rays. Glass doors are also poor insulators which mean that during the winter there will be major heat loss causing your energy bills to soar. Effective window treatments like blinds, shades and curtains do a fantastic job of addressing these concerns. There are blackout blinds, light filtering blinds, insulating shades, solar shades and a score of other ones that gives your windows the protection it requires. Blinds also help to add aesthetic interest and value to the windows and to the rooms.

Things to Consider When Buying Blinds

Type of Blind

Purchasing a blind requires substantial research. In the current  window treatment market you will be bombarded with different types of blinds which could make purchase a challenging task. Before setting out to get new blinds you need to determine the need of your blinds. Are you looking for blinds for greater light blockage or simple light filtration? Are you looking for enhanced insulation or heat control inside the house? Do you want to preserve your outside view or fool proof privacy from prying eyes? Will your blinds be exposed to moisture and humidity throughout the day or will be sun facing? Once you have recognized your need you can settle for your choice of window treatment.

Measurement of Door

But wait, before you rush to order your blinds, you need to get your doors measured. Measurement is critical for functionality of your blinds and also for aesthetic appeal of the room. An oversized blind will make your windows look poor while an undersized blind will fail to provide comprehensive coverage to the doors and windows. Even an inch here and there could make a significant difference to the appearance and functionality of your blinds.

Type of Mount

When you are measuring for blinds for your windows you have to consider the mount of the blinds that is whether they will be inside mount or outside mount. Inside mount blinds look sleek and smart but windows must have adequate depth. Outside mounts are good if you are looking for better coverage and if you have defective windows or ugly mouldings to hide. Door blinds are however generally outside mount as doors usually lack sufficient depth for the blinds to fit inside.

How to Measure?

To start with,

  • Measure the length and width of the glass.
  • For a raised moulding around the glass which you may want to cover, you have to measure from outside of the moulding edge to outside edge width and length. Remember to add an extra inch to the width and about 3-4 extra inches to the length for better privacy and insulation and also prevent light from escaping out of the sides of the blinds. Too much width will cause the blind to clash with the handles and locks.
  • Make sure that the tilt and lift options of the blinds are located next to the door hinges and away from the handle. Otherwise, closing and opening the door may interfere with the controls of the blinds. For doors with no mouldings you have to add about ½” to ¾” to the width to make sure that they don’t interfere with locks and handles. For the height you must add about 2” to the top and ½” to the bottom to make room for installation hardware and also for hold down brackets that are located at the bottom.
  • For doors that have lever handles, 2 and 2 ½ inch blinds work pretty well but the handle could interfere with the tilt operation of the blind slats. There are hold down brackets that help to keep blinds in place and prevent them from swinging back and forth. But you must add few inches to the height of your blind to allow for these hold down brackets below the glass.

Measurements for blinds for doors will vary slightly depending upon the type of blind you are ordering.

If you are measuring height of your wood or faux wood blinds then at the top you must add 2” for the mounting surface and 1 or 1 ½” at the bottom for hold down brackets.

For cellular shades it will vary depending upon the lift option.

For standard pull cord you must add 1” at the top for the mounting surface and 1 ½” at the bottom for hold down brackets.

For continuous cord loop and cordless you should add 2” at the top for the mounting surface and 1 ½” at the bottom for hold down brackets.

Doors can be either sliding or French doors with hinges

For both sliding glass doors and French doors you have to follow the procedure given below to measure the height and width of the blinds.

Width: You have to take three measurements at the top, middle and bottom. You have to take the largest width and then add about 2” to 4” for better light coverage. You should make sure that the width of the shade does not run into the door handle.

Height: You have to measure the height from top to bottom on left, centre and on the right side. Use the largest measurement for the height of your blind.

You can take measurements at home but you must be extremely careful not to make any errors as it can ruin the look and functionality of your blinds and as they are customized for you, you may not be able to get them exchanged. If you are unsure it is preferable to get professional assistance to help with the measurements.
