How many meters of molding do I need?

One of the most frequently asked questions we get from customers is: How do I know how many meters of molding I need for my wall?
In this guide, I'll explain step by step how to calculate this. This way, you can start using Flexlists independently without ordering too much or too little.

Step 1: my design

The first step is to determine exactly what kind of pattern you want on your wall. Think carefully about your desired layout: do you want one or more panels? A clean frame or playful shapes like arches? What visually complements the rest of your interior? Popular styles like wainscoting are also often found here. Your design will ultimately determine how many meters you need, so think carefully about this.

Because the possibilities for design are endless, we'll cover exactly how to create one in a future blog post. This is now very easy with AI.

Step 2: Measuring is knowing

In the second step, we'll measure the width of the wall where you want to place the molding. Let's look at an example.

In this example, we'll use a wall 4.80m wide and 2.50m high for the molding. We'll install three molding frames on this wall: two narrow frames on the sides and a wider one in the middle. We'll use this setup to calculate exactly how many meters of molding we need later.

Step 3: The layout of the wall

Let's consider a logical design based on the wall. Generally, leave about 10 to 15 centimeters of space between frames. This creates a calming look on the wall. You can, of course, choose more space between frames, but this depends on your taste and interior.

Now it is important to get the dimensions clear:

Element

Width (cm)

Left space (wall)

30

Narrow frame left

90

Left/center spacing

15

Middle management

200

Center/right spacing

15

Narrow frame on the right

90

Right space (wall)

30

Total

480 cm

Based on the design, we divide the 4.80-meter wall into separate sections. We leave 30 cm of space at the sides and 15 cm between the frames to keep the whole structure airy and symmetrical.

The total therefore comes to exactly 480 cm, or the full width of the wall. This arrangement forms the basis of your final calculation.

Step 4: the height of the frames

Now that we have determined the width division, let's look at the height of the frames.

A common rule of thumb is to maintain 65 to 75% of the wall height . This allows for sufficient space above and below, creating a sense of calm in the overall look.

This gives a frame height of 190 cm, with 30 cm of space above and below (for the skirting board and ceiling).

Step 5: Calculate

Now it's time to calculate how many meters of Flex frames are needed in total.

Based on our three-frame design, we'll calculate below exactly how many meters of molding you need. The width and height measurements for each frame result in the following total calculation:

Management position

Width (cm)

Height (cm)

Horizontal (2×)

Vertical (2×)

Total per frame

Left (narrow)

90

190

1.80 m

3.80 m

5.60 m

Middle (wide)

200

190

4.00 m

3.80 m

7.80 m

Right (narrow)

90

190

1.80 m

3.80 m

5.60 m

Subtotal





19.00 m

+ 10% cutting loss





+1.90 m

Total required





20.90 m

As you can see, the total required length is 19.00 meters. But we're not done yet, because you always have to deal with cutting waste. When cutting moldings to size, you always lose a small amount. Think of corners that aren't cut straight, small corrections, or cutting errors.

To ensure you have enough, we always recommend adding an additional 10% to the total. For example: If you need 19 meters, order approximately 20.90 meters, including cutting waste .

Cutting loss is not waste, but a safety margin that prevents frustration and ensures a professional end result.

Ready to get started?

As you've seen, calculating the correct amount of molding is primarily a matter of thorough preparation. By first clarifying your design and then using smart measurements and calculations, you'll avoid surprises during installation. And with a 10% margin for cutting loss, you're always on the safe side.

Whether you choose a sleek frame, multiple panels, or something more creative, you now have everything you need to get started with confidence.

FAQ: Velida Flex frames & installation

Not difficult at all. Thanks to Velida's self-adhesive Flex frames, you can get started without experience, glue or tools. You only have to mark where the Flex frames should go, cut to size and stick. We do advise to paint the Flex frames for the best effect.

Want to know exactly how the installation works? Read our installation manual here.

This depends on which design you would like to apply.

To help you get started, we've written a guide on how to easily determine how much length you need.

Yes. The frames are equipped with a high-quality adhesive strip that ensures long-term adhesion, even on smooth plastered walls or renovation fleece. Make sure that the surface is free of grease and dust.

Once you have pressed the molding firmly and the shape has become final, we do not recommend pulling it off again. The adhesive strip is very strong and ensures long-lasting adhesion, but can leave marks on painted walls when removed.

Absolutely. All Velida Flex frames can be painted over with wall paint. This way you can fully integrate them into your interior colour or create a beautiful accent wall with a tone-on-tone effect.

During application you can still carefully correct the Flex frames. We recommend that you first lightly draw the line with a pencil, so that you can follow the molding straight and tight.

For the best result, it is best to do this together: one person holds the Flex frames under tension, the other presses it precisely against the marked line.

Once you have pressed the molding firmly and the shape has become final, we do not recommend pulling it off again. The adhesive strip is strong and ensures long-lasting adhesion, but can leave marks on painted walls when removed.

Our tip: Take your time when marking and applying. That way you will make sure it will be installed correctly and you can enjoy the end result for years to come.

Yes, that is precisely the strength of the Velida Flex frames. Thanks to the flexible material, you can effortlessly apply round shapes and arch decorations without sawing.

Velida Flex frames are basically designed as a sustainable interior upgrade. But do you still want to remove them? You can, as long as you do this carefully and in a controlled manner.

Important: Always pull the moldings off slowly in sections. Start at one side and pull gradually, without jerking. This prevents damage to the wall or paint layer.

With firmly pressed frames (especially after a long period of time), the adhesive strip may adhere so well that paint may come off when removed, especially on vulnerable surfaces such as thin layers of paint or untreated renovation fleece.

Our tip: If necessary, warm the molding slightly with a hair dryer (lukewarm) before loosening it. This makes the glue a little more flexible and reduces the chance of damage.

Do you want to be 100% sure of damage-free removal in the future? Then first test on an inconspicuous piece of wall or choose to mount on well-painted, smooth surfaces.

Yes, the material is moisture-resistant and bends without breaking. However, the surface must be dry and flat during application.
