How Do I Choose the Right Width of Edge Banding for Furniture?

Choose an edge banding width that is slightly wider than the actual panel thickness, leaving enough material for trimming after application. A practical starting formula is:Edge Banding Width = Actual Panel Thickness + Trimming Allowance

For example, an 18mm furniture panel can be paired with 23mm edge banding, providing 5mm of additional width for trimming. Unilin Panels uses this 18mm panel → 23mm edge tape combination in its processing guidance.

For common furniture panels, a useful starting reference is:

Why Does Edge Banding Need to Be Wider Than the Panel?

Edge banding is normally applied to the exposed edge of a panel and then trimmed or milled flush with the panel surface.

That means the edge band cannot simply be the same width as the board thickness.

If you have an 18mm panel and use exactly 18mm edge banding, there is essentially no material available for trimming adjustment.

Instead, you need additional width so the edge band can extend slightly beyond both faces of the panel.

Example: 18mm Panel

Imagine an 18mm panel:

18mm panel + 5mm trimming allowance = 23mm edge banding

The additional material gives the machine enough room to:

• cover the complete panel edge
• compensate for small dimensional variations
• allow trimming on both sides
• create a clean finished edge
• reduce the risk of exposed substrate

After application, the excess material is removed during trimming.

This is why 23mm edge banding is a useful stocked width for many 18mm panels rather than simply being an arbitrary size.

How Much Wider Should Edge Banding Be?

There is no single width that works for every panel.

A good starting point is to allow approximately 4–5mm of additional width, but the correct value should ultimately follow your actual panel thickness and processing setup.

Unilin specifically recommends 5mm extra width for a clean finish.

For example:

18mm Panel

18mm + 5mm = 23mm

19mm Panel

19mm + 4–5mm = approximately 23–24mm

16mm Panel

16mm + 4–5mm = approximately 20–21mm

The important point is not to memorize one number.

Measure the actual panel first, then select the edge banding width based on your trimming.

What About 3/4-Inch Panels?

This is particularly important for the U.S. market.

A nominal 3/4-inch panel is approximately 19.05mm, but the actual thickness can vary depending on the panel product and manufacturer.

Therefore, don't choose edge banding based only on the nominal "3/4-inch" label.

Instead:

Step 1

Measure the actual panel thickness.

Step 2

Add the trimming allowance required by your process.

Step 3

Select the closest practical edge banding width.

For example:

19mm panel + approximately 4–5mm allowance = 23–24mm edge banding

This is one reason why 23mm edge banding can also be useful for U.S. cabinet and furniture applications.

Does Edge Banding Thickness Affect the Width You Need?

Not necessarily.

Width and thickness solve different problems.

• Width determines how much material is available to cover and trim the panel edge.
• Thickness affects the visual appearance, durability, machining behavior and edge protection.

For example, you could have:

• 23mm × 1mm edge banding
• 23mm × 2mm edge banding

Both are 23mm wide, but they have different thicknesses.

So don't choose width based only on edge banding thickness.

Instead, select them independently:

Width → based mainly on panel thickness and trimming allowance

Thickness → based mainly on application, appearance, durability and machining requirements

22mm vs. 23mm Edge Banding: How to Choose for 18mm Panels

For an 18mm panel, the choice between 22mm and 23mm edge banding comes down to the amount of material available above and below the panel after application.

The calculation is straightforward:

• 22mm edge banding − 18mm panel = 4mm total excess
• 23mm edge banding − 18mm panel = 5mm total excess

That extra width is used during the trimming process. It is not part of the finished edge; it provides the material needed to extend beyond the panel faces and then be trimmed flush.

22mm vs. 23mm at a glance

*Assuming the edge band is centered on the panel. Actual distribution depends on the machine setup.

What does the extra 1mm actually change?

The important difference is not that 23mm is “better” than 22mm. The difference is that 23mm gives the trimming operation an additional 1mm of total material.

On an 18mm panel:

22mm → 2mm excess per side

23mm → 2.5mm excess per side

That additional 0.5mm on each side can matter when the production process requires a little more trimming allowance or when panel thickness and edge-band positioning are not perfectly consistent.

This is particularly relevant in production because the nominal panel thickness is not necessarily the exact thickness of every sheet. Panel tolerance, edge-band dimensional tolerance and application positioning all affect the amount of material available for final trimming.

How to Choose Edge Banding Width Before You Place an Order

If you are purchasing edge banding for a furniture project, use this simple process.

Step 1 — Measure the panel

Don't rely only on the nominal specification.

Measure the actual finished thickness.

Step 2 — Identify the application

Is it:

• cabinet carcass?
• cabinet door?
• drawer?
• shelf?
• tabletop?
• office furniture?
• custom furniture?

Step 3 — Add trimming allowance

Use your machine/process requirements to determine how much extra width is needed.

A useful starting point is approximately 4–5mm extra width.

Step 4 — Select the closest practical width

For example:

18mm panel → 23mm edge banding

Step 5 — Confirm the machine setup

Check:

• edge banding machine
• trimming unit
• milling unit
• feed speed
• adhesive system
• edge banding thickness

Manufacturer processing guidance should take priority over a generic chart. Unilin, for example, specifically notes that the trimming unit should be matched to the edge tape thickness and recommends 5mm extra width for finishing.

Step 6 — Order a sample

Before committing to a large quantity, test the actual combination of:

panel + edge banding + adhesive + machine

This is especially important when appearance and color matching matter.

Common Mistakes When Choosing Edge Banding Width

Mistake 1: Choosing the same width as the panel

18mm panel → 18mm edge banding may leave insufficient material for trimming.

Better approach: allow additional width.

Mistake 2: Choosing the widest available option

Wider is not automatically better.

Too much excess material can increase waste and trimming requirements.

Better approach: choose enough width for reliable processing.

Mistake 3: Using nominal thickness instead of actual thickness

A panel labeled 18mm may not measure exactly 18.00mm.

Better approach: measure the actual panel when precision matters.

Mistake 4: Choosing width without considering the machine

Two workshops may use the same panel but different edge banding machines and processing settings.

Better approach: confirm the machine's trimming requirements.

Mistake 5: Focusing only on width

A correctly sized edge band can still produce a poor visual result if the thickness, material, color or texture is wrong.

Better approach: select the complete specification.

What Should You Tell Your Edge Banding Supplier?

Instead of simply asking for:“22mm edge banding”or“23mm edge banding”

give the supplier the complete specification:

Panel: 18mm MDF / particleboard / plywood
Edge banding material: PVC / ABS / Acrylic
Edge banding thickness: 1mm / 2mm
Width: 22mm or 23mm
Surface: Matte / Wood Grain / High Gloss / Soft Touch
Color: Panel-matched
Application: Automatic edge banding machine

This reduces the risk of selecting the correct width but the wrong material, thickness or surface finish.
