Measuring For Arches & Skylight Shades

Arches

First, measure the base width inside the arch opening.

Then measure the height at the middle (tallest) point inside of the arch opening

Other suggestions:

Most arches are imperfect (not a semi-circle), but it's better if you have the shade made perfectly, then use a sharp straight edge to trim the shade as needed. If your width is 60", then your height should be 30". You can also provide an exact template of the window, imperfections and all, and we'll have the arch made to the template.

Measuring Guidelines - SKYLIGHTS

With skylight shades, the procedures for outside mounts are the same as for standard rectangular shades.

With inside mounted shades:

Measure the width and height inside the window opening in at least three locations each.
If the window opening is longer than 96", measure the width every 48".

Order the narrowest width and the shortest height.

Round your skylight inside mount measurements up to the nearest 1/8", not down as with other inside mounts. The factory deductions take into account the application of compressible foam tape (rail seal) to the outside of the rails.

For fully recessed inside mounts, a 2" minimum mounting depth of the window opening is required. Non-flush mounted inside mounts are not recommended; but if necessary, a sklight shade may protrude up to 1/2". Note that mounting depths must take ino account any obstacles to shade movement, such as window cranks or handles.

Outside mounts require only a 1/2" flat surface for bracket attachment.

In addition to shade measurements, the angle of the window should also be noted on the order form.

Five Steps to an Accurate Template

1. Tape butcher paper or heavy wrapping paper over the window opening, allowing plenty of overlap. Use paper that has never been folded; a template can have no folds or creases.

2. Draw an exact outline of the window opening by carefully tracing over the inside edge of the window frame with a fine tip pen or marker.

3. Remove the paper from the window opening. If the shade is an outside mount, add the desired amount of overlap to the window outline and draw a second outline around it to match the shape of the finished shade.

4. Mark the shade dimensions on the template. Check that the template dimensions match your measurements of the actual window opening. It is easiest to verify by cutting out the template and repositioning in the window opening.

5. Identify the template and its orientation. Write your name on the template, and mark the "ROOM SIDE" and "TOP". Roll up the template and place it in a mailing tube to include with the order. Do not fold the template.
