You've got this! Just follow our simple steps.

Size range: Our roller shades fit windows from 24" to 118" wide and 24" to 120" high.

Before You Start

Grab these tools:

  • Metal tape measure (steel works best)
  • Phone notes or pen & paper
  • Step ladder (if needed)

Quick prep: Clear your window area, check for obstructions like handles or locks.

Important: Measure each window individually - even identical-looking windows can vary!


Step 1: Choose Your Mount

Pick what works best for your window:

Inside MountMost popular

  • Mounts inside the window frame for a clean, built-in look
  • Requires 2" minimum depth from glass to front of frame to allow bracket to fit property inside
  • Showcases your window trim
  • Maximum light blocking and privacy
  • Check for obstructions that might block shade operation

Outside Mount

  • Mounts on the wall around your window frame or ceiling
  • Covers the entire window frame and extends beyond it
  • Perfect for shallow windows (<2" depth) or blackout needs
  • Makes small windows appear larger

No Window Frame? (Ceiling Mount)

  • Mount directly to ceiling above window opening
  • Common for modern windows or architectural openings

Step 2: Measure Width

Inside Mount

Width: Measure across the top of window frame only, edge to edge Record exact measurements - we'll make the deductions. Round down to nearest 1/8" if absolutely needed. 

Outside Mount

Width: Add 2-3" on each side of window opening for light control. Measure straight across where brackets will mount. Final size will be exactly what you order.

No Frame (Ceiling Mount)

Width: Measure across the top of the window exactly where you'll want your shade to sit above it.


Step 3: Measure Height/Drop

For all mount types: Decide where you want your shade to end, then add 3-4" extra for better coverage. The extra length gives you flexibility and better light control.

Height measuring:

  • Use the tallest measurement of your window
  • Common ending points: windowsill, floor, or anywhere in between

Step 4: Record Your Measurements

Write them down as Width × Drop (W × D)

Width Rounding Rules:

  • Inside mount: Round down to nearest 1/8"
  • Outside mount: Round up to nearest 1/8"
  • Never round to nearest 1/2" or whole inch

Control side: Choose left or right for your chain or motor charging port

For manual shades: Pick the side with no obstructions for the chain to hang freely

For motorized shades: Choose a side easily accessible at the top of the window where your charging port will be located
