The patio doors, in particular, allow access to your outdoors or patio, they allow plenty of light to pour into the house and also offer a fantastic view of your outdoors. They are stunning to look at and accentuate the beauty of the house.

Beautiful as they may be, sliding patio doors have to be dressed up for a variety of reasons. They give an unobstructed view of your indoors from the outside which can compromise the security and privacy of your homes. Moreover, glass doors allow the loss of energy as they cause warm air to escape during the winter and allow the hot heat from the sun to pass through during summer. Too much of sunlight can also hurt the eyes, and interfere with your work and sleep. Its harmful UV rays can cause damage to your furniture and décor. For all these reasons, it is important to find the right window treatment for your sliding doors that will look classy and elegance and be functional at the same time. There are a number of blinds and shades options for you to choose from.

Measuring for Sliding Patio Door Blinds: Steps to Follow

The most critical part of getting your blinds to make a perfect fit is getting the doors measured accurately. To come up with the correct measurements you must take the following into considerations.

Step 1: Type of Blinds
There are two types of blinds, horizontal and vertical. Horizontal blinds are beautiful and are perfect for standard windows. For the large wide windows and doors, vertical blinds are more suitable. This is because sliding doors open on one side which exposes the door part while the rest of it remains covered. Cellular Honeycomb shades, pleated shades and roller shades are also good choice for sliding doors. If you opt for shades that go up and down then you need to decide whether you want one large shade/blind that will cover the whole door or you want to pieces, side-by-side shades that can be operated independently.

Step 2: Type of Mount
While inside mounts are fitted inside the window casing and do not cover the glass door’s border, outside mounts are fixed on the wall and cover the molding around the window area. The type of mount you choose depends upon your preference. Vertical blinds are generally mounted on the outside where the headrail is mounted above the window opening on the wall. Most of the shades are however inside mount and covers the windows only and the wall at all. Take into consideration the handle of the sliding door, and if it is too big then you will have decide whether the inside mount will be practical.

Step 3: Measurement of Width: Vertical Blinds
Inside Mount
• Measure the width of the window/door. Measure the exact width from the inside edge of the frame on the right to the inside edge of the frame on the left.
• Measure the top, bottom and center of the window/door. Identify which is the narrowest width of the three and round it to the nearest 1/8 inch.
• Provide 2.5 inches minimum depth for completing the installation of blinds inside the window/door.

Outside Mount
• For outside mounts, determine where you want the edges of the blind to extend on either side of the window. Vertical blinds will extend about 4-5 inches beyond the actual window while outside mount shades should cover about 1/1.5-2 inch of the wall on either side. The width of the window trim must be taken into consideration when measuring outside mount blinds and shades.

Step 4: Measurement of Height: Vertical Blinds
Inside Mount
• Measure the height of the window/door. If it is an inside mount then measure the height from the inside of the top of the window’s trim to the inside of the trim at the bottom.
• Measure the door on the left, right and center and take the tallest measurement and round it up to the nearest 1/8 inch. Take the measurement in such a way that the blinds sit just above the floor to prevent dragging of the vanes.

Outside Mount
• For outside mount, you will have to take measurement from the top of where the headrail is fitted, down to the floor. Vertical blinds should be mounted about 3 inches above the window opening. The vanes should not touch the floor and must fall just short of the floor.
• Unlike shades, height is very important for vertical blinds. For most shades, any extra will not be too noticeable (as the extra fabric will stack or stay in the roll).

Step 5: Double-check Measurements
Make sure that you recheck and record the measurements: first the width and then the height, and not the other way round.
Step 6: Measurement for Side-to-Side Shades
If you have opted for two side-by-side shades instead of one single then you must take care to measure both sides separately. Take special cognizance of the width of the frame around the part where the door moves to determine that there is no gap at the center from where the light will pass through. The shades should meet at the middle mullion of the door, which will help block any light that would come through the gap between the two shades.

Points to Remember While Measuring Sliding Patio Door Blinds

• To get the best measurements, use a steel tape measure.
• Don’t get confused between width and height measurements. Follow the width by height format always and mark them down.
• Measure them to the nearest 1/8 inch.
• There may be more than one door in the house but make sure to measure them separately. Never assume that all doors are of same size.
• If you are installing vertical blinds very close to wall heaters ensure that the blinds clear the heaters by 6 inches on the side and 12 inches on the top.
• There mustn’t be any obstructions on either side of the doors that might prevent you from fitting a wider blind.
• If there are any obstructions near the door then make sure to take measurements to the right and left of the door frames up to the closest obstructions.

Sliding glass doors look beautiful and the blinds you install should do justice to them. For that, the type of blind and fit is of utmost importance. A badly fitted blind either does not cover the doors or is hung to high or not only affects the functionality of the door but also damages the aesthetic sense of the house. To avoid this ensure that the doors are measured following the guidelines.
