Three steps to measure for BLOCSY

Step 1: Checking Your Window Recess Depth

Before measuring the width and height, make sure your window recess offers enough space for a smooth, built-in fit.

  • Minimum depth required: 1.18 in (3 cm) for secure installation.
  • How to measure: From the outer edge of the recess, measure straight to the nearest inner surface this gives you the true depth.

Measuring with Obstructions

Even with a deep recess, certain elements like handles or trims can interfere with the blind’s movement. To ensure a flawless fit:

  • Measure the full recess depth from the front edge to the window glass.
  • Measure the obstruction depth from the window to the front of the obstacle.
  • Subtract the obstruction depth from the recess depth to determine your clear space.

Note: A minimum of 1.18 in (3 cm) of unobstructed depth is required for a smooth and secure installation.

Step 2: Measuring the Width

Because most windows aren’t perfectly square, take three measurements to ensure a precise fit:

  • Top of the recess
  • Middle of the recess
  • Bottom of the recess

Use the smallest measurement it guarantees your blind fits neatly, even at the narrowest point.

Step 3: Measuring the Height

Now, measure the height of your window recess at three points to ensure perfect alignment:

  • Left side
  • Center
  • Right side

Record the smallest value it ensures your blind fits precisely from top to bottom.

Avoid Common Measuring Mistakes

To ensure perfect accuracy, keep these in mind:

  1. Avoid measuring at an angle: always keep your tape straight and level.
  2. Don’t bend the tape: even a slight curve can distort the result.
  3. Leave room for the insulation ribbon: subtract about 1 cm from your final width for a flawless fit.

Final Tips for Accurate Measurement

  • Be precise: take exact measurements; if needed, round to the nearest 1/16 inch (or 0.1 cm) for a perfect fit.
  • Let us handle the adjustments: just provide the exact width and height, and we’ll take care of any necessary deductions during production.
  • Measure from the front of the recess: that’s where the Guard will be installed, so accuracy at this point is ke
