This comprehensive reference covers measuring inside-mount, outside-mount, and specialized window blinds. High rise blinds manufacturers specialize in creating durable and stylish window treatments designed to meet the unique needs of tall buildings and urban settings

A Guide to Measure Blinds Accurately

Learn Blind Types and Mounts

Before measuring blinds, you must grasp their two major mounting options and types. An inside-mount or outside-mount installation can greatly affect your blinds’ appearance and functioning. Inside-mount blinds seem neat and built-in in the window frame. This mount is perfect for windows with enough depth for blinds and highlights the window frame with a sleek design. However, outside-mount blinds cover the entire window and sometimes the wall. This mounting option works for windows without enough depth for inside-mount blinds or for complete light blockage.

Blind Types

Your blind choice depends on your aesthetic tastes, functional needs, and window characteristics. Some common blinds are:

  •         Venetian Blinds: Tiltable horizontal slats control room lighting. Their versatility makes them suited for many window sizes.
  •         Vertical Blinds: Slatted vertical blinds are great for wide windows and sliding doors. They can tilt and draw to the side, making them useful for wide entrances.
  •         Roller Blinds: These minimalist blinds are made from one piece of cloth that rolls up. Easy to use, they come in several colors and materials.
  •         Roman Blinds: Soft, elegant fabric blinds fold up in parts. They come flat or hobbled, each with a unique look.
  •         Honeycomb (Cellular) Blinds: These energy-efficient blinds insulate with air cavities. They can function top-down or bottom-up and come in various cell sizes.
  •         Panel blinds: Large fabric panels on tracks for large windows or room dividers. They are contemporary and come in several fabrics and colors. Motorized blinds manufacturers are at the forefront of smart home technology, offering seamless and convenient window covering solutions that can be controlled with the touch of a button

Tools Required

Blinds must be measured accurately to fit well. Using the correct equipment will help you measure accurately and avoid costly mistakes. The following tools are needed:

  •         For precision, use a strong, retractable steel tape measure.
  •         Pencil and paper for measurements.
  •         Step Ladder: For taller windows.
  •         Level: For straight measurements.
  •         Optional Measuring Template: Some manufactures offer measuring templates.

Measure Inside-Mount Blinds

Inside-mount blinds are popular for their sleek, integrated design. To get a great fit, measure properly. Here’s how:

  •         Measure Width: Measure the top, middle, and bottom window opening width. Record the narrowest width to ensure blinds fit the frame.
  •         Height: Measure the left, middle, and right window opening heights. Record the longest height for complete coverage.
  •         Check Depth: Measure the window frame depth to ensure blinds fit. This is crucial for honeycomb and Roman blinds. For homeowners seeking modern and functional window treatments, roller shades in White Rock offer a versatile solution that complements a wide range of interior styles

Accurate Measurement Tips

  •         Steel tape measures are precise.
  •         Measure to 1/8 inch.
  •         Measure twice for accuracy.
  •         Note the width first and height second (e.g., 35 1/4″ W x 60 1/2″ H).

Outside-mount blind measurement

Outside-mount blinds are perfect for shallow windows or complete light blocking. Outside the window frame, these blinds conceal more. Blinds in Richmond come in a variety of styles and materials, offering residents a plethora of choices to enhance their home decor while ensuring privacy and light control. How to measure them:

  •         Measure the Width: Determine the blinds’ extension beyond the window frame. For best light control and privacy, blinds should reach 1.5 to 3 inches beyond the window frame on each side. Include the overlap in the width measurement.
  •         Height Measurement: Choose the blinds’ mounting height above the window frame. Allow a few inches below the window frame for full coverage when measuring from this point to the desired length.
  •         Check for Blockages: Avoid handles and trim that could interfere with blind operation.

Accurate Measurement Tips

  •         Steel tape measures are precise.
  •         Measure to 1/8 inch.
  •         Measure twice for accuracy.
  •         When measuring, write width first and height second (e.g., 38″ W x 64″ H).
  •         Measurement for Special Windows
  •         Bay, arched, and skylight windows require special attention. Measure for these unique window types:

Bay Windows

Three or more bay windows project beyond the outside wall. Bay window blind measures require various measurements per section:

  •         Measure Sections Separately: Measure the width and height of each window portion as you would a regular window.
  •         Consider Angle: Measure the window section angles to ensure blinds fit smoothly.
  •         Clearance, depth: Allow enough depth and clearance for blind operation.

Arched Windows

Blind measurements for arched windows might be difficult, yet they offer elegance to any room:

  •         Width: Measure the window base width.
  •         Height: Measure the arch from base to peak.
  •         Template: Custom blind manufacturers may demand an arch template. Follow their template creation and submission guidelines.


Skylights are hard to hide but provide natural light. Skylight blind measurements:

  •         Width: Measure the skylight’s widest point.
  •         Skylight Height: Measure the skylight’s longest point.
  •         Depth and Clearance: Allow enough space for the blinds to work.

How to Avoid Common Measurement Errors

Blinds can be measured easily, but frequent mistakes can cause ill-fitting. Avoid these risks with these tips:

  •         To avoid inaccurate measurements, use a steel tape measure and measure twice.
  •         Unmeasured Dimensions: For inside-mount blinds, measure width and height at numerous places (top, middle, bottom and left, middle, right) to allow for differences.
  •         Not Considering Depth: For thicker blinds, make sure the window frame is deep enough.
  •         Not Considering Obstacles: Examine handles, locks, and other impediments that may affect blind operation.
  •         Recording Measurements Incorrect: Record width first, height second, and measures to the closest 1/8 inch.
