How Many Window Coverings Are Necessary To Span 50 Windows​

If you're planning a large-scale window treatment project—such as for a commercial office, apartment complex, or multi-room home—you may be wondering: How many window coverings are necessary to span 50 windows? Here's a step-by-step breakdown to help you plan effectively.

Determine How Many Windows One Covering Can Handle

Window treatments such as blinds, shades, or curtains are often made to the size of each window. But in some cases, such as with larger-than-average or bespoke treatments (for example, one extra-wide shade for a row of windows), treatment width might cover more than one windowsill.

Let’s say:

A single covering can cover 15 windows (e.g., as within a continuous window wall).

You’ll need to tackle 50 separate windows!

Then:

50 ÷ 15 = 3.33 → 4 curtains 3 ¹/₃ →Round this to 4 covering.

✔️ You will need 4 large-window coverings.

Common Scenarios

Covering Span per Unit	Number of Windows	Required Coverings
1	50	50
5	50	10
10	50	5
15	50	4

Always round up, since you can't install a partial window treatment.

FAQ: How Many Window Coverings Are Necessary to Span 50 Windows?

If you have 50 windows, you do not always need 50 separate window coverings — it depends on how your windows are arranged and the look you want.

• One Covering per Window: This is the most common option, especially for bedrooms, offices, or anywhere you want independent light control. For 50 windows, you would need 50 shades or blinds.

• One Covering for Multiple Windows: If you have several windows side by side, a single extra-wide shade or drapery can cover two or more windows at once. This gives a cleaner look, reduces the number of products you need, and can save money on installation.

Tip: For large projects like offices, schools, or whole-house renovations, we recommend measuring all windows and sending the sizes to us. We can help you plan the most cost-effective combination of single and multi-window coverings — which often reduces the total number needed.
