How to Measure Sliding Glass Doors for Blinds
Sliding doors and patio doors need special consideration for window treatments. This guide covers measuring for vertical blinds, panel tracks, and more.
Best Blind Options for Sliding Doors
Vertical Blinds
Classic choice for sliding doors. Individual vanes rotate for light control and slide open for door access.
Panel Track Blinds
Modern alternative to verticals. Wide fabric panels slide on a track. Clean, contemporary look.
Cellular Vertical Shades
Vertical orientation of honeycomb shades. Energy efficient with a soft, fabric look.
Sheer Vertical Shades
Fabric vanes between sheer layers. Elegant, diffused light with privacy and view-through options.
Inside vs Outside Mount
Outside Mount (Recommended)
Blinds mount on the wall above the door frame and extend beyond the sides.
- Better light blockage
- Door operates freely
- Makes door appear larger
- Covers frame imperfections
Inside Mount
Blinds fit inside the door frame. Requires deep frames (3+ inches).
- Clean, built-in look
- Shows off trim work
- May interfere with door
- Needs 3"+ frame depth
Step-by-Step Measuring (Outside Mount)
Measure the Width
Measure the width of the door frame, then add overlap:
Width = Door frame width + 6-8 inches
Add 3-4" on each side for overlap
Example: 72" door frame + 8" overlap = 80" total width
Measure the Height
Measure from where blinds will mount to just above the floor:
Height = Top of headrail to 1/2" above floor
Mount 3-4" above door frame
Example: If mounting 4" above a 80" door opening, and door opening starts 1/2" from floor: Height = 84"
Check Headrail Clearance
Ensure there's space above for the headrail:
- • Vertical blinds need 4-6" above mounting point
- • Panel tracks need 3-4" clearance
- • Check for crown molding, vents, or lights
Determine Stack Direction
Where should the blinds stack when open?
Stack Left
Stack Right
Split Center
Choose based on which side your door opens from - stack blinds on the fixed panel side.
Pro Tips for Sliding Door Blinds
Match stack to door operation
If door slides right to open, stack blinds on the left (fixed panel) side
Consider split draw for wide doors
For doors over 96", split draw opens from center for easier operation
Add wand control for safety
Cordless wand operation is safer with kids and pets near doors
Consider motorization
Remote control is convenient for large, heavy blinds
Check vane/panel width options
Wider vanes (3.5") or panels look more modern than narrow ones
Measure floor to mounting point
Vanes should hang 1/2" above floor - not dragging
Frequently Asked Questions
What are the best blinds for sliding glass doors?
Vertical blinds (affordable, easy), panel track blinds (modern look), cellular vertical shades (energy efficient), or sheer vertical shades (elegant). Your choice depends on style and budget.
Should sliding door blinds go inside or outside the frame?
Outside mount is recommended. It provides better light blockage, doesn't interfere with door operation, and makes the door appear larger.
How much should blinds overlap a sliding door?
Extend 3-4 inches beyond each side of the door frame and 3-4 inches above for proper light blockage and a finished look.
Can I use regular horizontal blinds on a sliding door?
While possible, horizontal blinds aren't ideal. They can be heavy, may sag, and the door can't be used when lowered. Vertical options are better suited.
