One room. A separate record for every opening.

Keep your raw readings and unresolved questions together. This worksheet does not approve a product’s fit or calculate an order size.

No room plan was provided. You can record an opening here or start with the room planner.

1 opening in this worksheet · up to 30. Switching keeps each opening’s notes on this page.

Opening 1

Raw opening readings, in inches

All readings are optional. Use a positive number or fraction, such as 35.375 or 35 3/8. For an outside mount, keep these separate from your planned coverage size.

Next: review with the seller

Keep the unknowns visible.

For Opening 1, mark what you have reviewed. These are your notes, not verified fit or a completed order.

0 of 4 review items marked.

Resolve questions about fit, coverage and ordering rules before submitting dimensions. A checked box does not confirm product compatibility.

Measuring guidance for this opening

SelectBlinds’ standard cellular guide uses the smallest opening width and largest height. Keep all your readings, then check the exact product’s measuring and rounding instructions, especially for no-drill options.

Check the chosen configuration’s mounting and flush requirements, surface suitability, handles, cranks and sensors. No-drill and specialty options can have different rules.

Category sources reviewed November 2, 2026. Use the current instructions for your exact product and options; a different retailer may use different rules.

Keep the whole worksheet.

Save only when you choose. This browser keeps one saved worksheet; saving replaces that copy. Downloads and prints include every opening, your room choices and your seller-review notes.

No account or email is needed. Names, readings and notes stay on this page, in a file you request, or in this browser if you save. The tool does not send them to our server or analytics. Save or download before leaving.

Before you submit an order

Follow the exact product’s ordering instructions and check the seller’s current cancellation, return and remake terms before ordering.

  1. Use a steel tape measure and record the bare opening before applying any product-specific rounding or coverage rules.
  2. Keep all three widths: top, middle and bottom. The seller’s product guide determines which reading to use.
  3. Keep all three heights: left, middle and right. The height rule can differ by product and mount.
  4. Measure clear mounting depth and note obstructions such as handles, cranks, trim and sensors.
  5. Confirm minimum mounting space, flush depth, lift options and frame compatibility in the exact product’s specifications.
  6. For an outside mount, follow the product guide for overlap, bracket position and finished coverage. Keep the opening measurements separate.
  7. Confirm factory deductions and no-drill or specialty exceptions. Do not subtract or add to an order dimension without the seller’s instructions.
  8. Recheck each window separately, review samples and the seller’s current remake terms, then confirm your final order dimensions with the seller.
