Why Accurate Measurements Matter
Measuring your windows wrong is an expensive mistake. A window that is even half an inch off may not fit, leading to delays, extra costs, and return shipping fees.
Even small errors can push back your installation by weeks. This guide will help you take accurate measurements for estimates and browsing our in-stock inventory.
We always recommend a professional measurement before placing a final order. But this guide gives you a great starting point — whether you are in Fort Lauderdale, Miami, Boca Raton, or West Palm Beach.
Step-by-Step Measurement Guide
Measure Width (Left to Right)
Measure from stucco to stucco on the outside of your home.
Take three measurements:
- Top of the opening
- Middle of the opening
- Bottom of the opening
Use the smallest of the three measurements.
Measure Height (Top to Bottom)
Measure from the top of the opening to the sill.
Take three measurements:
- Left side
- Center
- Right side
Use the smallest of the three measurements.
Check Depth (Optional)
Measure the wall depth from the outside edge of the frame to the inside edge.
This helps determine the right installation type for your impact windows.
Write Everything Down
Always record measurements as Width × Height.
Example: 36" × 60" means 36 inches wide and 60 inches tall.
Label each window by room and location (e.g., "Living Room — Left").
Important Tips
- Always measure from the OUTSIDE of the home
- Do NOT guess sizes — measure every window
- Do NOT round numbers — use exact measurements
- Double-check everything before ordering
- Measure each window individually — they are rarely the same
Common Mistakes to Avoid
- Measuring from inside only — always go outside
- Using trim or casing as reference points instead of the actual opening
- Measuring only one spot instead of three
- Rounding numbers up or down
- Assuming all windows in the same room are the same size

Frequently Asked Questions
Should I measure from inside or outside?
Always measure from the outside. Measure from stucco edge to stucco edge (or frame to frame) for the most accurate opening size.
What if my measurements are slightly different at each point?
That is normal. Always use the smallest measurement for both width and height. This ensures the new window will fit the opening.
Can I measure windows myself for an order?
Self-measurement is fine for estimates and browsing inventory. For a final order, we strongly recommend a professional measurement to avoid costly errors.
How do I write down my window measurements?
Always write measurements as Width x Height. For example, 36" x 60" means 36 inches wide and 60 inches tall.
