Ordering wall molding is exciting, but taking a few measurements before you buy can save hours of frustration during installation.

You don't need to be a contractor or have complicated tools. In fact, a simple tape measure is enough to gather everything needed for a custom wall molding layout.

Here are the ten measurements we recommend collecting before ordering your kit.

---

1. Overall Wall Width

This is the most important measurement.

Measure from one end of the wall to the other, excluding adjacent walls.

Even a difference of a few inches can completely change the panel layout and spacing.

How we can help: Every WondrWallz kit is custom-sized based on your exact wall width.

2. Wall Height

Measure from the finished floor to the ceiling.

Ceiling height affects panel proportions and determines whether a full-height or half-wall design will look best.

---

3. Baseboard Height

Don't forget the baseboards.

Different homes have baseboards ranging anywhere from 3" to over 8", and this changes where the first panel should begin.

Tip: Measure from the floor to the top of the baseboard.

---

4. Window Locations

Measure the width of each window and its distance from the nearest wall.

This helps keep panels balanced instead of cutting awkwardly around the windows.

---

5. Door Openings

Include every door on the wall.

Measure:

• Door width
• Distance from the wall
• Door casing width

This allows the molding layout to flow naturally around the opening.

6. Chair Rail Height (For Half Walls)

If you're installing a half-wall design, decide approximately where you'd like the chair rail.

Most homeowners choose somewhere between 32" and 42", depending on the room and ceiling height.

Don't worry if you're unsure—we're happy to recommend the ideal height for your space.

7. Outlets, Switches & Thermostats

Electrical boxes don't always have to be avoided, but knowing where they are helps create a cleaner design.

A quick photo is often enough.

---

8. Vents & Air Returns

Floor vents, wall vents, and return air grilles can affect panel placement.

Measuring them in advance prevents unexpected adjustments during installation.

---

9. Furniture Placement

Will there be:

• A bed?
• Sofa?
• Buffet?
• TV?
• Fireplace?
• Dining table?

Large furniture changes how the wall is viewed, and often influences where panels should begin and end.

A perfectly centered layout on an empty wall isn't always the best layout once furniture is in place.

---

10. Take One Photo of the Wall

The most valuable measurement isn't actually a measurement.

A clear photo helps identify details that numbers can't show, including:

• Trim
• Windows
• Doors
• Outlets
• Vents
• Crown molding
• Baseboards
• Obstacles

One photo often answers questions before they become problems.
