The Sizefield on the Form Attributes frame is a display-only field and reflects the current size of the form, as determined by editing on the Form Layout frame, or in the case of pop-up display-style forms, by the VisuallyAdjust operation.

When using this information to plan the location of a pop-up form, remember to account for the additional lines and columns required for a specified border. The pop-up and its border must be small enough to entirely fit within the window.
