Free In-Home ConsultationHow to Measure & Install Vertical Blinds
Things to Remember:
- Use a steel tape for accuracy.
- Measure Width and write it down, then Length and write it down.
- Measure to the nearest 1/8 inch.
- Do not take your own deductions. The factory will take necessary deductions and allowances.
- Double check all measurements.
- NOTE: All measurements should come from measuring the window. If you measure your existing blinds, the measurements will be incorrect.
Inside Mount Installation
To find width:
Measure the opening across the top where the headrail is to be installed from inside of jamb on left to inside of jamb on right. Record the exact measurement to 1/8″.
To find length:
Measure from the inside top of the opening on the left, at the center, and on the right to the sill; record the measurement to the nearest 1/8”. Do not make any allowances; the factory will make all adjustments so the headrail will fit the opening properly and the vanes will clear the sill by 1/4″ to 1/2″.
Outside Mount Installation
To find width:
Measure the width of the area to be covered at the place where the headrail will be installed to the nearest 1/8″. Blind should overlap opening at least 4″ on each side to ensure privacy.
To find length:
Measure the length of the area to be covered and record to the nearest 1/8″. Blind should extend at least 3″ above and 3″ below opening or window molding. For ceiling-to-floor installations, make adequate allowance for carpeting. Specifying “OB” measurement means the factory makes no deduction allowances.
Patio Doors
To find width:
Measure the width of the area to be covered at the place where the headrail will be installed to the nearest 1/8″. Blind should overlap opening at least 4″ on each side to ensure privacy.
To find length:
Measure the length of the area to be covered and record to the nearest 1/8″. Blind should extend at least 3″ above opening or window molding. For ceiling-to-floor installations, deduct 1/2″ for proper clearance. Specifying “OB” measurement means the factory makes no deduction allowances. To ensure easy access through the door and allow adequate overlap, consider the stack width.
