Measuring the Width and Length for a Reveal Fit (Inside)
A Reveal Fit is when your Outdoor Blind fits snugly within the recessed area or between posts.
To Measure, We need four measurements:
1) Top Width inside the opening.
2) Bottom Width inside the opening.
3) Left-Side Height inside the opening.
4) Right-side Height inside the opening
Order Size: Order the Shortest Width & the Longest Height.
Reveal Fit Pro Tips:
- Double-check your sizes.
- If the width difference between the top and bottom is 10mm or less, you’re good to go. If they vary by more than 10mm, don’t worry; you can still Face Fit or use packing to level your opening.

Measuring the Width and Length for a Face Fit (Overlap)
A Face Fit is when your Outdoor Blind overlaps the opening; ideal for hiding hardware or areas with handrails.
To Measure, We need four measurements:
1) Top Width overlapping the opening by 100mm overall (50mm on each side).
2) Bottom Width overlapping opening by a minimum of 100mm (50mm on each side).
3) Left-side Height overlapping opening by a minimum of 100mm overall.

- Height variations are common, often for water to drain away from the house.
- 100mm Height overlap is the minimum; it’s a good idea to add more if you have the space to hide hardware – 150mm overall is ideal.
