Independent retailer notice: Home Builder Blinds is an independent window-treatment retailer and is not affiliated with, endorsed by, or sponsored by KB Home. “KB Home” is a trademark of its respective owner and is referenced here only to describe the kinds of production-built homes our blinds commonly fit. The window patterns below describe general production-home tendencies, not any builder's proprietary specifications. Always measure your own windows before ordering.
Why KB Home Window Sizes Vary More
KB Home’s "Built to Order" model and Design Studio let buyers choose structural options, elevations, and upgrades. Two KB homes on the same street can have different window configurations, so there is no single size table that fits every home — accurate measuring is the reliable path.
- Buyer-chosen options mean more variation between neighboring homes
- Optional window upgrades can change widths and add windows
- Standard widths still cluster in the 34.5"–58" range for bedrooms and standard rooms
- Larger optional windows push some openings to 70.5"+
Most Common Blind Sizes
These are the widths you are most likely to hit after the ~½" inside-mount deduction — but treat them as a starting point and measure every window:
| Window opening | Typical blind width | Common room |
|---|---|---|
| 35" | 34.5" | Bedrooms |
| 47" | 46.5" | Kitchens, baths |
| 58" | 57.5" | Living rooms |
| 71" | 70.5" | Upgraded/large windows |
For the complete opening-to-blind chart, door and sidelight sizing, and room-by-room ranges, see our standard builder blind sizes guide.
What KB Home Owners Usually Buy
Since every blind is custom cut to your measurement anyway, KB owners pick by look and budget — usually starting with faux wood and adding roller shades where they want a cleaner look:
- 2" faux wood blinds — The most popular all-purpose choice, custom cut to your exact opening.
- Roller shades — A clean, modern option that is a popular upgrade for living areas and larger windows.
- 1" vinyl mini blinds — Budget-friendly for secondary rooms while you finish the rest of the home.
How to Confirm Your Exact Size
The patterns above are a starting point — your specific floorplan and any builder upgrades can shift them, so always measure. Measure each opening's width at the top, middle, and bottom and height at left, center, and right. For an inside mount, report the exact opening and the factory deducts about ½" for clearance; for an outside mount, add 1.5–2" of overlap per side. Our measuring & installation guide has step-by-step instructions.
Frequently Asked Questions
What size blinds do I need for a KB Home?
Because KB Home is built to order, window sizes vary more than with a fixed-spec builder. Common widths still fall in the 34.5"–70.5" range, but you should measure each opening individually rather than rely on a standard chart.
Why are my KB Home window sizes different from my neighbor’s?
KB Home lets buyers personalize floorplans, elevations, and window options at build time, so two homes in the same community can have different window configurations. That is why measuring your own openings is essential.
Do I need custom-size blinds for a KB Home?
Our blinds are custom cut to your measurements regardless, so you are not limited to off-the-shelf sizes. Provide your exact opening width and height and choose inside or outside mount — the factory applies the standard deduction for inside mounts.
How do I measure my new KB Home windows?
Measure width at the top, middle, and bottom and height at left, center, and right of each opening. For an inside mount, report the exact opening and let the factory deduct ~½". See our full measuring guide for step-by-step instructions.
