Mobile: Swipe to rotate, pinch to zoom, two-finger drag to pan.
Note: The 3D visualisation simplifies the design by showing only the width and thickness dimensions. The actual moulding will have the profile design matching your selected style seen in the image below (Astragal, Florence, etc.), though the visualisation shows them as simple rectangular strips. Each moulding also has its own fixed thickness and width.
Materials Required
How Will I Receive My Order?
Your wall panel moulding will be delivered in full-length strips (2440mm, 3050mm, or 4200mm), as selected. This allows for flexibility on-site, giving you the control to cut each moulding piece to the exact dimensions required for your custom layout.

What is the Length Option?
Wall panel moulding is supplied in three sizes, 2440mm (2.44m), 3050mm (3.05m), and 4200mm (4.2m). Some panel mouldings like Inset, only have one length option. You'll receive the full length of moulding required to complete your wall according to your specifications, regardless of which length you choose. The amount of excess material may vary depending on the option you choose, and the price will also vary. Shorter lengths are often more suited for smaller projects and are easier to handle, whereas longer lengths may require fewer cuts.
What is the Finish Option?
The finish option allows you to customise the paint of the moulding. You can choose to have the moulding undercoated (sprayed white, sanded, with primer and undercoat applied), primed (sprayed white with primer applied), unprimed (left as bare material), or matt grey.
Excess Material
Excess material indicates the length of material which is not required for your panelling configuration. However, during cutting and installation, material will be lost, so the excess material ensures you have enough to complete your project. If you're unsure, we recommend adding a couple of extra moulding strips in the checkout.
Moulding Details
Moulding Width: This is the width of the moulding profile. Width varies depending on the moulding.
Moulding Thickness: This is the thickness of the moulding profile, affecting how far it protrudes from the wall surface. Thickness varies depending on the moulding.
Note: Panel moulding style is simplified in the visualisation. The actual profile will match your selected moulding style as seen in the images. Skirting board is not included in your order, and is available at our sister site skirtingworld.com.

Installation Tips & Best Practices
Our wainscoting calculator provides all the measurements you need, but here are some professional tips to ensure successful installation:
Plan Your Layout
Before cutting any material, mark the wall with masking tape or pencil lines to visualise the panel layout. This helps identify any unforeseen obstacles or adjustments needed.
Perfect Mitred Corners
When cutting mouldings for corners, set your mitre saw to exactly 45° and make test cuts on scrap pieces first. Apply wood glue to mitred edges for added strength.
Secure Attachment
Use a combination of panel adhesive and finishing nails or pins for the most secure installation. This provides immediate hold while the adhesive cures.
Professional Finish
Fill any gaps at joints with decorators caulk or wood filler. Once dry, sand smooth and apply your chosen paint finish for a seamless appearance.

Frequently Asked Questions
Wainscoting is a specific type of decorative wall panelling that typically covers the lower portion of a wall. Traditionally, it extends around 1/3 to 1/2 of the way up a wall and is topped with a chair rail. Unlike full wall panelling, wainscoting creates a two-tone effect with different treatments for the upper and lower portions of the wall. Our calculator allows you to design both traditional wainscoting and full-height panelling options.
Our calculator offers several classic moulding styles for your wainscoting project:
- Astragal: A timeless profile with a gentle curve (25mm × 15mm)
- Inset: A slimmer, more subtle design ideal for modern spaces (20mm × 9mm)
- Astragal Large: A bolder version of our classic Astragal (34mm × 17.5mm)
- Florence: An elegant, wider profile for more substantial panelling (54mm × 17mm)
- Astragal Maxi: Our most substantial Astragal profile (40mm × 25mm)
- Vienna: A sophisticated, wide profile for grand interiors (72mm × 24mm)
- 324: A versatile, medium-sized profile with clean lines (30mm × 16mm)
Each style creates a different aesthetic effect while maintaining the classic appeal of wainscoting.
Our calculator provides highly accurate estimates of the exact moulding lengths required for your specific design. It calculates the total linear meters needed based on your wall dimensions, panel configuration, and chosen moulding style. The calculator then determines how many standard lengths (2440mm, 3050mm, or 4200mm) are needed to fulfil your requirements, including a small amount of excess material to account for cutting waste. This precision ensures you order exactly what you need—no more, no less.
The "Panel Fit" option allows you to control how panel widths are distributed across your wall. Options include:
- Equal Panel Widths: All panels have identical widths
- Adjust End Panels: Adjusts only the leftmost and rightmost panels
- Spread Left/Right: Creates a focal point on one side
- Spread Both Ends: Emphasizes both outer edges
- Centre Focus: Makes central panels wider for emphasis
- Outer Focus: Creates wider panels at the edges
- Alternating: Creates a rhythm of wider and narrower panels
The slider below the dropdown allows you to fine-tune the intensity of the effect, giving you precise control over your panel proportions.

This PDF serves as your definitive reference guide during installation, ensuring you have all the information you need at your fingertips.
Our MDF panel mouldings are moisture-resistant and can be used in bathrooms and kitchens with proper sealing. For these areas, we recommend:
- Using our moisture-resistant MDF mouldings
- Applying a high-quality primer specifically designed for humid environments
- Finishing with moisture-resistant paint or sealant
- Ensuring all edges, especially bottom edges near floors, are properly sealed
With these precautions, your wainscoting can thrive even in moisture-prone areas. For wet areas that come into direct contact with water, consider our PVC panelling options instead.
For a professional wainscoting installation, we recommend having:
- Mitre saw or mitre box with handsaw
- Tape measure and pencil
- Level (preferably a long one)
- Caulking gun for adhesive
- Brad nailer or hammer with finishing nails
- Sandpaper (various grits from 120-220)
- Wood filler or decorators caulk
- Primer and paint (if not using pre-finished moulding)
- Painter's tape
