DIY Measure Guide

Rough measurements are enough to get started

You don’t need perfect numbers to design and price windows online. Take a few rough measurements, plug them into the configurator, and we’ll verify everything on-site before anything is built.

Your online quote is a starting point. A professional confirms exact sizes at your home, and pricing updates if anything changes — no surprises after the fact.

Width

Jamb to jamb — top, middle, and bottom. Use the smallest.

Height

Sill to head — left, center, and right. Use the smallest.

  1. 1

    Gather what you need

    A tape measure, a notepad (or your phone), and a few minutes per window. Measure from inside the house — no need to remove trim or the old window.

  2. 2

    Measure the width

    Inside the window frame (jamb to jamb), measure the width at the top, middle, and bottom. Write down all three. Use the smallest number — that’s your rough width for the configurator.

  3. 3

    Measure the height

    Measure from the top of the sill up to the head jamb on the left, center, and right. Again, use the smallest number as your rough height.

  4. 4

    Round to the nearest inch

    For an online quote, whole inches are fine. If you’re between inches, round down slightly so your estimate stays conservative. We’ll take exact measurements later.

  5. 5

    Enter sizes in the configurator

    Pick your window style, then enter width and height in inches. You’ll see pricing update as you go. Add each window to your quote with a room name if you want (Kitchen, Master Bedroom, etc.).

Quick tips

  • Measure each window separately — sizes often differ room to room.
  • Don’t include the exterior trim or brickmold in your numbers.
  • If the opening is out of square, still use the smallest width and height.
  • Snap a quick phone photo of each opening if you want us to double-check later.
  • When in doubt, estimate a little smaller rather than larger for the online quote.
