Why bay and bow glass needs panel-by-panel sizing
Angles change both visible width and mount depth. A single big-box blind will gap or bind on the corners.
- Center panel is usually widest
- Flank panels may be narrower and steeper
- Sill depth varies — confirm inside-mount clearance
- Outside mount can hide uneven returns
- Keep color identical across all panels

Mounting by material & situation
Choose mount from depth and obstructions first, then pick vinyl, faux wood, or rollers for the room’s moisture and light needs.
1" vinyl mini blinds
View product line →Wipe-clean vinyl for baths, secondary rooms, and moisture-prone openings.
Inside mount — adequate depth
Measure width at top, middle, and bottom. Order the narrowest reading. Confirm ~1" clear depth for the headrail.
- Min depth:
- ≈ 1" clear
Outside mount — shallow frames
When returns are thin or trim eats depth, outside-mount on flat casing with overlap on each side.
After water exposure
Replace swollen or moldy treatments with vinyl — do not reinstall damaged fabric or wood.
2" faux wood blinds
View product line →Moisture-resistant PVC faux wood for living areas — not untreated real wood.
Inside mount — living rooms
Pro often usedNeeds more depth than mini blinds. Measure both top corners before assuming inside mount.
- Min depth:
- ≈ 1½"–2½"
Outside mount on builder trim
Production casings sometimes leave uneven returns — outside mount keeps the headrail square.
Roller shades
View product line →Clean fabric lines for wide glass, sliders, and blackout sleeping rooms.
Inside mount cassette
Pro often usedConfirm unobstructed depth for the tube and brackets. Deduct per product rules when ordering.
- Min depth:
- Check cassette depth
Outside mount / face mount
Use when mullions, handles, or shallow returns block inside mount — common on sliders and storefront.

Frequently asked questions
Can one blind cover a whole bay window?
Usually no. Order a blind per panel so each facet operates cleanly and closes without light gaps at the angles.
What product looks best on a bay?
2" faux wood is the most common living-room choice. Vinyl mini can fill small flanks on a budget.
Should I outside-mount bay blinds?
Outside mount helps when inside depth is uneven. Keep overlap consistent so the set still reads as one composition.
