How to Measure for a Window Well Cover in Toronto
How to Measure for a Window Well Cover in Toronto
Quick answer: Measure three dimensions: A, width from side to side at the wall; B, projection from the wall to the outside edge; and C, height from the top edge of the well up to the top edge of the window. Record the measurements and take photos so the cover can be assessed for your specific opening.
This A/B/C method follows Window Well Covers’ window well measurement guide. It gives you a useful starting point for an estimate. Window wells can vary in shape and condition, so final cover sizing should account for the actual opening, the window and any nearby obstructions.
What do A, B and C measure?
- A — Width: side to side at the wall.
- B — Projection: from the wall to the outside edge of the well.
- C — Height: from the top edge of the well up to the top edge of the window.
Keep the labels with the numbers as you write them down. That makes it easier to understand the dimensions when you send them for an estimate.
How do you measure a window well?
- Measure A: measure the width across the well at the wall, as shown in the guide.
- Measure B: measure outward from the wall to the well’s outside edge.
- Measure C: measure from the top edge of the well up to the top edge of the window.
- Record the units: write down whether each number is in inches or centimetres, and use the same unit for all three.
If an edge is uneven, note that and take a photo. Do not guess at a standard size if the opening is irregular.
What else should you check before requesting a cover?
The three measurements describe the well, but the cover also needs to work with the window and the area around it. Note whether the window opens outward, slides, or has another style. Include visible handles, trim, siding, stairs, a deck, pipes or other obstacles near the well. A clear photo from above and one from the side can help show the shape and available space.
If the basement window is an emergency egress window, tell the installer. The cover design must preserve access from inside; confirm how the proposed cover opens before ordering. Never assume a cover supports a person’s weight or foot traffic unless the manufacturer confirms its rating.
How should you measure an irregular window well?
For a curved, sloped or uneven well, still record A, B and C, then take photos that show the full opening and its edges. If the well has different widths or projections at different points, note where you measured and include the variation. The installation team can review the details and advise whether additional measurements or an on-site visit are needed.
Common measuring mistakes to avoid
- Writing down numbers without labeling them A, B or C.
- Mixing inches and centimetres.
- Ignoring a sloped or uneven edge, window handle or nearby obstruction.
- Assuming the well is a standard rectangle when it is not.
- Choosing a cover before confirming the window can open and egress access is maintained.
