Shutter Measurement Guide — Inside Mount Only

Welcome to our guide for measuring your new shutters! This guide applies to inside mount shutters only. By following the clear steps and taking accurate measurements, you’ll ensure a perfect fit, smooth installation, and a clean, beautiful finished result.

Before You Begin — Inside Mount Shutters

Choose inside mount if:

  • The window is a frame-less drywall opening with sufficient depth for installation.
  • The window opening is square and structurally sound.
  • You want the shutters installed neatly inside the window opening.
  • You prefer a clean, built-in appearance.

Note: Measure diagonals to confirm the window is square.

Cafe Style Shutters:

  • Frame Sides: Left, Right, Bottom (top is open)
  • Description: Cover only the lower portion of the window, leaving the top open for natural light.
  • Recommended for: Spaces where privacy is needed at the bottom but natural light is desired, such as kitchens, dining areas, and living rooms.
  • Benefits:
    – Provides privacy while letting light from top
    – Creates a bright, airy, relaxed European-style
    – Decorative appeal, aligns with window grids, mid-rails, decor

Full Height Shutters:

  • Frame Sides: All sides (top, bottom, left, right)
  • Description: Cover the entire height of the window from top to bottom.
  • Recommended for: Maximum privacy, light control, and sturdiness. Ideal for bedrooms, bathrooms, or street-facing windows.
  • Benefits:
    – Full coverage for privacy and shading
    – Adjustable louvers for precise light control
    – Clean, unified look inside the window frame

Measure Your Window for Inside Mount Shutters

(For Full Height & Cafe Style Shutters)
Welcome! Follow these 4 simple steps to get accurate measurements for your inside-mount wooden shutters. Correct measurements ensure a perfect fit and smooth installation.

① Check the Depth

Depth: Measure Bottom Left, Bottom Right, Center Left, Center Right;

Ensure it’s sufficient for a stable inside mount.

② Check the Width

Width: Measure Top, Middle, Bottom; use the smallest.

③ Check the Height

Full Height: Measure Left, Center, Right; use largest.

Cafe Style: Measure Left & Right from sill; align with grids/mid-rails.

④ Check the Diagonals

Squareness: Measure Bottom Left → Top Right and Bottom Right → Top Left;

Difference ≤ 1/2" → window is square for inside mount.

Measurement Check — Inside Mount

Now you have all the necessary window size data. The next step is to determine whether your window opening is suitable for an inside mount.

  • If the opening is square
    Your window is suitable for an inside mount. These measurements can be used to order your shutters. Round each measurement down to the nearest 1/8".
  • If the opening is not square
    An inside mount may not fit properly and could affect both installation and operation. In this case, we recommend choosing an outside mount for a better fit and improved performance.

Inside Mount Important Notes

  • Ordered width = narrowest width
  • Diagonal difference must not exceed 1/2"; if it does, an inside mount is not recommended
  • Confirm the window has sufficient depth for an inside mount; if not, consider an outside mount or other suitable options
  • Ensure the window frame or opening is sturdy enough for direct installation
  • For Cafe Style shutters, please confirm the desired café height
