Vertical Blind Sizes: Standard Widths, a Size Chart, and Custom Limits

Vertical blinds have no single standard size, because each blind is sized to the opening it covers. On a sliding patio door, the opening is usually 60, 72, or 96 inches wide and about 80 inches tall. Value Blinds makes its sheer-fabric vertical blinds to order in any width and height from 20 to 117 inches, in 1/8 inch steps.

Vertical Blind Size Chart

Use this chart to match your opening to a blind size. Sizes for Value Blinds orders are shown against our 20 to 117 inch limits.

What Size Vertical Blinds Do You Need for a Sliding Glass Door?

Sliding patio doors are usually 60, 72, or 96 inches wide and about 80 inches tall. Those are nominal sizes, and some doors are taller, so measure the door you have rather than ordering from the nominal size.

Choose an outside mount if the door handle or a shallow frame leaves no room for an inside mount.

Outside mount width rule: measure the width of the door frame and add at least 2 inches on each side, so at least 4 inches in total. A 96 inch door with 2 inches of overlap on each side needs a 100 inch blind, which is within the 117 inch maximum we make in a single blind.

Outside mount height: measure from where the headrail will mount down to the point where you want the vanes to stop above the floor.

When the blind is open, the vanes stack together at the side and still cover part of the opening. If you want the glass and the door handle clear when the blind is open, extend the blind further past the frame on the side it opens toward.

What Sizes Can You Order From Value Blinds?

Here is what you can order on our sheer-fabric vertical blinds:

Every blind is made from the measurements you enter, so you do not need to adapt a stock size to your window. Our blinds carry a 3-year warranty and ship with free standard shipping (oversize packages may carry an added fee). If you would rather not measure yourself, we offer professional measuring and installation across the U.S. through our partner, National Blinds Installation.

What Is the Widest Vertical Blind You Can Order?

The widest single vertical blind we make is 117 inches. For a wider opening, order two blinds that meet in the middle, and split the total width so each blind stays at or under 117 inches. A 180 inch inside mount opening, for example, splits into two 90 inch widths.

With two blinds, each half opens on its own. Plan which side each blind opens toward before you order, and choose the wand position to match.

The tallest blind we make is also 117 inches.

Inside Mount or Outside Mount: Which Size Do You Enter?

The number you type into the order form depends on the mount:

• Inside mount. Enter the exact width and height of the window opening, not the size of the blind. Our factory makes a small deduction from the width so the blind fits snugly inside the frame, and adjusts your measurements for fit. Do not subtract anything from the width yourself, or the deduction will be taken twice.

• Outside mount. Enter the exact size of the blind you want. Our factory makes the blind at exactly that size, so include the overlap on each side in the width you enter.

Inside mount needs at least 2 1/2 inches of depth in the frame, and the valance needs at least 4 inches. If your frame is shallower than 2 1/2 inches, choose outside mount.

How Do You Measure for Vertical Blinds?

Use a steel tape measure and record every number to the nearest 1/8 inch. Measure the width at the top, middle, and bottom, and the height on the left, center, and right. For an inside mount, use the smallest width and the smallest height, and check that the frame is at least 2 1/2 inches deep. For every step in detail, see our guide on how to measure for vertical blinds.

 

How Do You Size Vertical Blinds for Bay and Corner Windows?

Each flat section of a bay window gets its own blind. Measure every section separately, because the side sections are often narrower than the center.

A corner window needs one blind on each wall. Measure each wall section on its own, and decide which blind runs into the corner so the two do not overlap.

Frequently Asked Questions

What is the standard size for vertical blinds?

There is no single standard size. Vertical blinds are sized to the opening. A sliding patio door is usually 60, 72, or 96 inches wide and about 80 inches tall. Value Blinds makes vertical blinds from 20 to 117 inches wide and tall.

What size vertical blinds do I need for a sliding glass door?

Measure the door frame and add at least 2 inches on each side for an outside mount. A 72 inch door takes a blind about 76 inches wide, and a 96 inch door takes one about 100 inches wide.

Can vertical blinds cover an opening wider than 117 inches?

Yes. Order two blinds that meet in the middle, each 117 inches wide or less. A 180 inch inside mount opening splits into two 90 inch widths.

Should I round up or down when measuring for vertical blinds?

Neither. Record each measurement to the nearest 1/8 inch. For an inside mount, enter the exact opening width and height, and let the factory make the width deduction.

How much depth do vertical blinds need for an inside mount?

Our vertical blinds need at least 2 1/2 inches of frame depth for an inside mount, and at least 4 inches to fit the valance.
