Double hung
Full window screen
Covers the upper and lower portions because both window sashes can typically open.
Full and half window screens
The screen coverage should match how the window opens.
Double-hung, single-hung, side-slider and casement windows use different screen sizes and mounting positions. Best Screens measures the actual opening and operating sash.
Coverage by window type
Full screen, half screen or the operable side.
Single hung
Half window screen
Covers the lower portion because that is typically the only sash that opens.
Horizontal side slider
Operable-side screen
Covers the side that opens. Although it covers one side, the screen can be similar in overall size to a full window screen.
Casement
Interior full screen
Mounts on the inside because the casement sash swings outward.
Installed screens
Full screens fitted across a group of windows.
Measure the complete screen
Size is only one part of a proper replacement.
Frame profile, corner construction, crossbar location, pull tabs, springs, plungers and other attachment hardware can affect fit and removal. Photos of the original screen and window help identify these details.
Mesh condition
Whitening can signal worn fiberglass mesh.
Fiberglass screen is vinyl coated. As the coating wears away, the fiberglass strands show through and the mesh can appear white or pale. Replacement mesh can restore the appearance and insect barrier.
