When it comes to choosing the right shutters for patio doors, getting the perfect fit is everything. Misaligned or ill-fitting shutters not only compromise aesthetics but can also affect functionality. That’s why it’s crucial to measure your shutters on patio doors accurately before making a purchase. But don’t worry—measuring doesn’t have to be complicated. 

In this guide, we’ll walk you through a step-by-step process to ensure you get the best fit for your space.


Why Proper Measurements Matter


Just think about it; you get those stunning shutters for your patio doors but they are too small to fit, or worse, they are too big. When the shutters are too big, they will make the door operation a bit difficult and they will look bulky. When they are too small, you will have gaps and they are not good-looking.


That is why accurate measurements are the key to get the smooth polished look of the custom patio door shutters that you want.


What You'll Need


First of all, now gather the tools below:


  • A metal tape measure (to be accurate)
  • A notepad or phone to jot notes of the given measurements
  • A level (for a perfectly aligned result)
  • A second set of hands (not necessary but can be helpful)


Step-by-Step Guide to Measuring Your Patio Doors for Shutters


1. Determine Your Mounting Style


There are two primary mounting options for shutters on patio doors:


  • Inside Mount – The shutters fit within the recess of your patio doors, offering a clean and built-in appearance.


  • Outside Mount – The shutters are installed outside the door frame, ideal for doors with limited depth.


Choosing between these two will impact your measurements, so decide which style works best for your space.


2. Measure the Width


Take the measurements of the frame in the recess at the top, middle, and bottom points. The smallest recorded size must be taken into account when the shutters are constructed. When mounted outside, measure from one outer edge of the door frame to the other.


3. Measure the Height


Measure at three points again, namely the left, center, and right. When it comes to shutters for the patio, the longest measurement should be taken to guarantee the covering of the whole area.


4. Consider Clearance and Obstructions


Consider the way your patio door shutters will work in terms of operation. Are there handles, locks, or trim that are around the door opening and closing that could cause interference with them? Recount those aspects when you are measuring the size of the door shutters.


5. Double-Check Everything


Remember that the precision of your measurements can define the success of the whole procedure! It would be wise to check the dimensions at least twice before submitting your order for patio door shutters. This is because errors in measurements can be very costly to resolve
