Understanding Inside Mount vs. Outside Mount Roman Shades
In determining the measurement in the calculation of Roman shades, the first thing to do is to determine whether to have an inside mount or an outside mount. This option is going to transform the appearance and use of your shades.
Inside Mount

Roman shades are fitted tidily in your window.
Benefits:
- Sleek, clean appearance.
- Keeps trim visible.
- Perfect in the minimalist contemporary room.
Remember: The mounting brackets should be sunk in at least 1½ deep in the frame.
Outside Mount

Outside mount shades are those that are fitted on the wall or mold of your window.
Benefits:
- Perfect for shallow frames.
- Increases the additional blockage of light.
- Enhances the size of small windows.
When you are deciding on the mounting style, then you are able to make precise measurements that suit your design objective.
How to Measure for Roman Shades: Inside Mount Method
You would like a close, fitted appearance, then here is how to cut Roman shades to an inside mount:

Step 1: Measure Window Width
Measure the width of the framing at three points—top, middle and bottom of the window frame—with your tape measure.
Record the smallest width (to the nearest 1/8 inch). This makes sure that your shades do not rub the sides.
Step 2: Measure Window Height
Measure then to the bottom sill of the frame at the top of the inside of the frame. Once again, record a reading on the left, center and right.
Record the longest height.
Step 3: Check Window Depth
Measure the distance between the front of the casing of the window and the glass.
Make sure that it is of the correct minimum depth required on the shade manufacturer's list (usually 1 to 2 inches).
How to Measure for Roman Shades: Outside Mount Method
An outside mount is better in case you want more control over the lights or you simply want to conceal the window trim. In this case the Roman shades can be measured as follows:

Step 1: Measure Width
Measure the precise width of the window aperture, and increase it by 3-4 inches on every side.
This overlap assists in blocking the extra light and also enhances privacy.
Step 2: Measure Height
Begin measuring where the top trim is (where you will put the shade) 2-3 inches above and 2 inches below the sill or as low as you want the shade to be hung.
An addition of height will make your windows look more complete and taller.
Step 3: Mark Mounting Points
Draw a horizontal line where the brackets are going to be with a pencil and a level. Straight-line maintenance gives the lines a smooth installation and a steady movement of the shade.

How to Measure for Roman Shades on Special Windows
Windows come in various shapes. Here's how to measure for Roman shades on non-rectangular windows:
- Bay Windows: Measure each section and record the angles.
-
Arched Windows: Measure to cover the upper part of the arch; shades may not cover the entire rectangle.
-
French Doors: Use outside mount dimensions, adding 1 inch around to cover completely.
For unique windows like showcases, custom fabrication may be needed, but accurate measurements are essential.

How to Measure for Roman Shades for Different Rooms
All the rooms in your house might need a minor variation in measuring:
- Living Room: Provide more width in order to block the sunlight and eliminate glare.
- Bedroom: The Bedroom should be lined with blackout and full outside mounts as much as possible.
- Kitchen: Have shades well above counters or sinks so that they are easy to clean.
- Bathroom: Make sure it fits well to retain privacy and keep the dampness away.
It is better to measure, taking into consideration room-specific conditions that guarantee better performance and style.
Measuring for Multiple Windows of Different Sizes
In case your home has multiple windows, which are different in size, label them:
- "Living Room: Left Window"
- "Living Room: Right Window"
- "Bedroom 1: Center Window"
Group similar sizes with the ease of ordering. You may even cut off to the nearest 1/8 inch when there is a slight difference in the size of two windows.
Common Mistakes to Avoid When Measuring Roman Shades
It is not difficult to learn how to measure for Roman shades when you know what to avoid. Minor errors result in ill-fitting and ill-hanging shades.
- Failing to measure in three positions: Windows are not necessarily always square. Measures at varying points at all times.
- Rounding numbers: Rounding down to width and up to height is always good in order to obtain the best fit.
- Stones to disregard: Be watchful of cranks, handles, or locks on the windows that may have an influence.
- Frame depth check omission: Especially in inside frame mounting, a lack of sufficient depth may render installation impossible.
These errors are time- and money-saving.
Tips for Getting Professional-Looking Results

Your shades can appear as though they have been installed by a professional even though you are doing it yourself. These are some of the fast tips to come up with a project that stands out:
- Apply regular methods of measurement to all the windows.
- Mark measurements with labels (i.e., Living Room Left Window).
- Never place any order without checking twice.
- Select fabric styles and colors that go with your room decoration.
- Consider the lining options in the event that you require a blackout or light-filtering control.
With these little tips, it is easy to make your Roman shades look polished and smooth.
Double-Checking Your Measurements Before Ordering
Always look at what you have recorded before you place your order.
Check this shortlist:
- Did you take the three points of the width and height?

An end-of-line check is a guarantee that makes your shades fit perfectly upon delivery.

4. Do Roman shades need the same depth as zebra blinds?
Most of the time yes, however, scrutinize the specifications of your product. The standard Roman shades require 1½ inches of frame depth.
5. Can I use the same measurement method for all window types?
