How to Measure

Symphony Shades are a snap to order and install, and measuring for your best fit is no different!

Here's what you'll need:

Step 1: Determine Shade Location

Symphony Shades can be installed inside or outside of the window frame.

We recommend an Inside Mount if you:

  • Have at least 1/2" of mounting space inside the frame.
  • You want your window frame to be visible. Folks generally prefer this look!

We recommend an Outside Mount if you:

  • Have too little mounting space inside the window frame, but at least 3/4" on or above the frame.
  • Are treating a door - this is usally more convenient.
  • Want to keep out more outdoor light.

Once the mounting location is decided, refer to the corresponding Inside and Outside Mount categories for detail on measuring and depth requirements!

Inside Mount

Mounting Space

Inside Mounts are only applicable if there is the proper amount of mounting space within your window frame. If there is hardware such as hinges, handles, etc, that get in the way of the minimum mounting space, you might want to consider an outside mount.

Depending on how much depth is available within the frame, your shade could be a shallow mount or a flush mount. 

Shallow Mount is when you have the between 1/2" to 1 15/16" of flat mounting space. There is the required depth to securely install the brackets, but front of the shade that projects into the room from within the frame. 

Flush Mount is when you have 2" or more (or 2 1/4" for Smoothy, Cordless, and Motorized shades), so the brackets and shade can hang within the window frame without any part of the shade protruding into the room. The shade is fully encased within the frame.

Each headrail type has its own mounting requirements. Take a look at the following chart to understand how much space is needed for Inside Mount applications.

Minimum Shade Mounting RequirementsStandard & Top Down Bottom Up (with strings) Smoothy Cord Loop, Cordless & Motorized*
Shallow Inside Mount 3/4"   1/2"
Flush Inside Mount 2" 2 1/4"
Shallow Inside Mount with Energy Saving Sidetracks 1 1/2" 1 5/8"
Minimum Flush Inside Mount with Energy Saving Sidetracks  2" 2 1/4"

How to Measure - Inside Mount

  • Gather your measuring tape, pencil, and Measuring Guide. You're off to a great start!
  • When you write down your measurements, list width first, then height. 
  • Width - For the most accurate measurement, measure the top, middle, and bottom of the window opening. Choose the narrowest width.
  • Height - For the most accurate measurement, measure the left, middle, and right of the window opening. If you're ordering sidetracks with your shade or if you are measuring for a skylight, choose the shortest length. If you are not ordering sidetracks, choose the longest length.
  • Deductions. Production will deduct a small amount of fabric from the width of the shade to ensure that the rails and fabric fit perfectly inside the window frame. All you have to do is provide the exact measurements that you take. You are not responsible for taking any deductions.
  • Please order to the nearest 1/8". Round down to the nearest eighth inch for width. If you are getting sidetracks, round down for length. If you are not getting sidetracks, round up for length.
  • It's always a good idea to measure twice for total accuracy. It ensures a perfect fit!

Outside Mount

Mounting Space

Installing your shade outside of the window frame is great when you have a door or need a shade but don't have the inside mount depth. It's also a handy trick if you're trying to make your window look bigger! 

You don't need a whole lot of space for an Outside Mount, but before you begin taking your shade dimensions, consult the mounting requirements below to make sure you've got enough flat space:

How to Measure - Outside Mount

  • Gather your pencil, measuring tape, and guide. 
  • When you are taking and ordering your dimensions, please write the width first, then the length.
  • A good rule of thumb is to measure where you want the shade to cover. It can help to mark on the window frame where the shade will hang.
  • Measuring the Width: Once you have your parameters set, measure the top, middle, and bottom. Choose the narrowest width. Add a few inches to each side if you'd like more coverage.
  • Measuring the Height: Measure the left, middle, and right side, from the top of the window frame down to the sill. Take the longest length. Add at least 1 1/2" to the length if there is no window sill.
  • We don't take any fabric deductions from Outside Mounted window shades.
  • Please take all measurements to the nearest 1/8". 
  • Since we make all shades precisely as ordered, it's always a wise idea to measure twice! This makes the measuring process as easy and accurate as can be!

Skylight Shades

Measuring for skylights is very much like measuring for reqular windows, but we have a special guide for those guys anyway, because there are a few other measuring details to consider. Click here for our Skylight Measuring Guide! 

Energy Saving Sidetracks

Sidetracks are the greatest thing since cellular window shades. They help add even more insulation! To make sure you measure just right, use our energy saving sidetracks measuring guide.
