How to Measure Your Windows
Watch our step-by-step video guide below to learn how to measure your windows precisely for inside mount.
Start With the Right Tools
Steel Tape Measure
A firm steel measuring tape gives you the most accurate reading. Fabric or soft tape measures can flex and give you incorrect numbers.
Pen and paper to record measurements
Write down each measurement as you go. Recording your numbers immediately prevents any mix-ups between windows.
A Simple Measuring Process for Every Window
Measuring Your Window Recess Depth
Before recording your window's width or height, always start by checking the depth of your window recess. This ensures your Haven Shades have enough clearance to sit perfectly inside the frame without any obstructions.
- Minimum Required Depth: 1 inch (2.54 cm) is required for a proper, flush installation.
- How to Measure: Begin at the front edge of the window recess and measure straight back to the back recess.
Watch for Obstructions
Check for any handles, window locks, latches, or protruding fixtures inside the recess before finalising your depth measurement. If anything reduces the usable depth.
Common Measuring Mistakes
- Always keep your measuring tape straight and level. Measuring at an angle will affect your final fit.
Final Tips for Accuracy
- Record measurements to the nearest 1/8 inch for the most accurate fit.
- Always double-check your width and height before placing your order.
