Full frame dimensions and the lower operable sash.
Double-hung
Full frame dimensions and both operable sashes.
Casement
Frame size, hinge side and crank condition.
Awning
Full frame size and operator condition.
Fixed & picture

Measure the pane itself and photograph markings or corner stamps.
Use it with GlassQuote
Measure enough for the estimate. Do not guess final order sizes.
The guide is intentionally short. Measure what you can safely see, add a straight-on photo, and use Custom Size in the estimator when the standard size choices do not fit.
Important: online measurements are planning measurements only. Final production, safety-glazing and installation dimensions are confirmed before ordering.
Best photo to send
One clear straight-on photo usually answers the next question
