Measuring Window Openings

Tip -To – Tip

When given a TTT measurement SWS will use the exact width and height dimension furnished, no deductions.   You window will be made that exact size.  Please measure carefully as customer-furnished measurements are the customer’s responsibility.

Measuring by the opening size

Pertains to an existing window frame where sash has been removed but the window frame has been left in place to house the new unit.  SWS when given an opening size dimension we will deduct 1/4″ off  the width and 1/2 ” off the height of dimension to allow room to square up the opening after installation.

Determine united inch

To determine united inch, add the height and the width.  If you have any questions, please do not hesitate to call SWS for answers.    Download replacement window measuring sheet.
