Window Labeling and Window Grouping

How window measurements are depicted in the measurement PDF

Updated over 4 months ago

Understanding the way in which Hover labels a structure's windows, and how the window grouping calculations are displayed, will help you complete your estimates that much quicker!

In this article, we cover how your structure's window measurements are depicted in the Hover measurement PDF.

Window Labeling


Throughout the measurement PDF, you will see various sketches, like the one pictured below, with a specific label assigned to each window following the naming convention W-101, W-102, etc:

These labels correspond to the Windows table, and make it easier to look up measurements for any one specific window.

The order in which the structure's windows are labeled, no matter the size of a structure, is as follows:

  • Beginning with the lowest level, left-to-right, you'll see labels such as W-101, W-102, etc.

  • The second level windows, labeled left-to-right, read as W-201, W-202, etc.

  • The third level windows, labeled left-to-right, read as W-301, W-302, and so on.

NOTE: If the property includes a walk-out basement with windows, the windows on that level will be labeled as W-001, W-002, etc.

Window Grouping


Any windows of a structure that share the same trim will be labeled as a Window Group (WG). Contracting organizations find this information very useful when preparing estimates per opening.

In the Windows chart of the PDF, you will find the Groups labeled sequentially as WG-1, WG-2, etc. A collective group measurement is also displayed under the column headings Group Width x Height and Group United Inches.

NOTE: Window Groups are not displayed on the interactive 3D model. Instead, you'll see each individual opening labeled on the model as W-101, W-102, etc.

Prefer to see the individual window measurements of a window group?

No problem! The individual window opening's width, height, united inches, and area square footage measurements are all included in the same Windows chart.
