How to Accurately Measure Walls for Wall Panelling Installation

Want to know how to measure walls for wall panelling? Our handy guide has you covered…

To accurately measure walls for wall panelling installation, use a tape measure to record the total wall width and height, factoring in skirting boards, dado rails, and coving.

Double-check for uneven surfaces, plan your panel layout to ensure symmetry, and mark precise reference lines with a spirit level before cutting any panels.

What Is Wall Panelling and Why Should You Use It?

Wall panelling is a cheat code for making your home look more expensive—without spending a fortune.

It involves attaching wood, MDF, or PVC panels to your walls to create texture, depth, and that all-important feature wall moment. Whether you’re into shaker-style, board and batten, or vertical panels, panelling instantly upgrades your space from “meh” to “magazine-worthy.”

But it’s not just about looks. Decorative wall panels also add character, protect your walls from scuffs, hide imperfections (because, let’s be honest, not all walls are created equal), and can even help with insulation.

The catch? If you want a smooth finish, you can’t just wing it. Accurate measurements are the difference between a polished, professional look and a DIY disaster.

So, let’s make sure you get it right the first time.

1. Understanding Different Types of Wall Panelling

Before you start measuring, you need to know what you’re actually measuring for. Different styles of decorative wall panels require different techniques, and picking the wrong one for your space is a recipe for frustration. Here’s a quick breakdown:

• Shaker-style wall panels – Clean, classic, and great for symmetry lovers.
• Board and batten – The go-to choice for adding texture without going full Tudor mansion.
• Slat panels – A modern, Scandi-inspired option that adds depth to a room.
• Wainscoting – Half-wall panelling that gives a period home that extra bit of elegance.

And then there’s the material to consider. MDF panels are budget-friendly and smooth, real wood panels give you natural texture, and PVC panels are great for bathrooms where moisture is an issue. Choose wisely—you’ll be living with it for a while.

2. Tools & Materials You’ll Need (No, You Can’t Just Guess)

To measure and install wall panels properly, you’ll need more than just enthusiasm. Here’s what to grab before you start:

• Tape measure (because “about this much” isn’t an actual measurement)
• Spirit level (unless you like your panels at a jaunty angle)
• Pencil & masking tape (for marking your reference points)
• Hand saw or mitre saw (because panels don’t cut themselves)
• Wood primer & paint (for that all-important finishing touch)
• Sandpaper (smooth edges = professional finish)
• Grab adhesive & decorator’s caulk (for a secure, seamless look)

3. How to Measure Your Walls for Panelling

Step 1: Measure the Total Wall Space

You’d be surprised how many people forget to measure properly before buying their panels. Don’t be one of them.

• Measure the total width and height of your wall in millimetres (accuracy matters).
• Account for skirting boards, dado rails, and coving—unless you fancy an awkward gap.
• Check if your wall is actually straight (spoiler: most aren’t). If it bows or dips, you’ll need to adjust your panels accordingly.

Step 2: Plan Your Panel Layout

There’s nothing worse than realising halfway through that your panels don’t line up properly. Avoid the frustration by planning your layout:

• Decide on the panel arrangement (grid pattern, vertical panels, full-height panels, etc.).
• Sketch it on paper or use a design app—guesswork isn’t your friend here.
• Mark reference lines on your wall using a spirit level.
• Check symmetry around plug sockets, light switches, doorways, and windows—unless you like things looking off-centre.

Step 3: Calculate Panel and Gap Sizes

Because maths is so much fun, here’s what you need to do:

• Work out how many panels you need and factor in gaps between them (this is crucial for shaker-style and board and batten projects).
• Use a spacer tool or masking tape to mark uniform gaps.
• Adjust your layout slightly to avoid awkwardly small panels at the edges—trust us, it’ll look weird.

Step 4: Double-Check Everything

Measure twice, cut once—or ignore this step and enjoy buying more panels later.

• Go over all your measurements again.
• Dry-fit some sample pieces to confirm spacing before making any cuts.

4. Preparing and Cutting Your Panels

Once your measurements are solid, it’s time to cut your panels.

• Mark cut lines clearly—no one wants a wonky panel.
• Use a mitre saw or hand saw for precision.
• Sand the edges down for that smooth finish.
• Prime and paint before installation—it’s much easier than painting after they’re on the wall.

5. Prepping Your Walls for Installation

You wouldn’t apply makeup without washing your face first, so don’t apply panels to dirty, uneven walls.

• Fill holes and cracks, then sand for a flawless base.
• If painting behind the panels, go for a matching base colour.
• Wipe down the wall—dust is the enemy of a strong adhesive bond.

6. Installing the Panels (The Fun Part)

• Dry-fit panels first to check everything lines up.
• Apply grab adhesive to the back of each panel.
• Press the panel onto the wall, starting with the verticals.
• Use a spirit level to check alignment before the adhesive dries.

7. Filling Gaps & Finishing Touches

For that seamless, high-end look:

• Use decorator’s caulk to fill small gaps.
• Sand smooth and apply a final coat of paint.
• If using natural wood panelling, add a protective finish to keep it looking sharp.

8. Final Checks & Styling Tips

• Step back and inspect your work—this is the moment of truth.
• Fix any uneven edges before everything sets.
• Consider adding wall sconces, framed art, or decorative trim to finish the look.

The Bottom Line

A flawless panelled wall starts with accurate measurements and proper planning. Take your time, double-check your numbers, and don’t cut corners (literally or figuratively). The result? A stunning feature wall that looks like a professional did it.

Wall Panelling Installation FAQs

1. Can I install wall panels myself, or do I need a professional?

Absolutely, you can install wall panels yourself! In fact, DIY wall panelling is one of the more manageable home improvement projects—assuming you have a bit of patience and the right tools. A nail gun, wall plugs, and a countersink drill bit will make the job much easier. If you want a smooth finish, make sure your panels are cut accurately, and always fill any drilled holes with poly filler before painting.

If you’re after easy installation, panelling kits are a great option since they come pre-measured, reducing the risk of errors.

2. Should I remove skirting boards before installing decorative wall panels?

Not necessarily. Many people install decorative wall panels directly above existing skirting boards for a cost-effective and hassle-free approach. However, if your skirting is particularly thick and affects the alignment of your panels, removing and refitting it may give you a cleaner look. Just be sure to measure your wall width carefully before making a decision.

3. How do I attach wall panels to the wall?

You’ve got a few options when it comes to securing panels to the wall:

• Grab adhesive – Great for MDF panels, providing a strong, seamless bond.
• Nail gun – Speeds up the process and is ideal for wood panelling.
• Wall plugs and screws – A more secure option if fixing panels onto a small cavity or plasterboard.

For a professional result, always use a spirit level to keep your panels straight, and don’t forget to fill any gaps with poly filler before applying a second coat of paint.

4. Do I need to re-plaster before installing new panelling?

Not always. If your wall is in decent condition, you can install new panelling straight onto it. However, if there are large cracks, peeling paint, or uneven surfaces, you might need to re-plaster or at least sand it down to ensure a smooth finish. If the wall sizes are uneven, adjusting your panels cut to fit the space is a smarter (and less messy) solution than plastering everything over.

5. How much does it cost to panel a wall?

The cost of paneling a wall depends on the materials you choose. MDF wall panels are the most cost-effective, whereas real wood panels tend to be pricier. You’ll also need to factor in the cost of adhesives, a nail gun, paint, and finishing materials.

If you’re on a budget, panelling kits can be a smart choice, as they come pre-cut and ready for installation. The size of the room, the complexity of the design (e.g., horizontal panels vs. full-height), and whether you hire a professional will all affect the final cost.

6. What are the best rooms for wall panelling?

Wall panelling adds a touch of aesthetic appeal to almost any space. Some of the best places to use decorative wall panels include:

• Living rooms – Adds depth and character, making a space feel more refined.
• Bedrooms – Perfect for creating a statement feature wall behind the bed.
• Hallways – A practical way to protect walls from scuffs and marks.
• Home offices – Elevates the space with a polished, professional look.

For the best result, always choose a desired colour that complements your existing décor.
