How to measure your artwork to choose the right-sized mount board
The mount board used for picture framing is a key element in both the aesthetic presentation and the long-term conservation of any artwork. Its main function is to create a visual space that provides balance and enhances the readability of the subject. It also prevents the glazing from coming into direct contact with the surface of the piece, which is essential for works on paper or items of heritage value. When selecting a mount board, it is important to consider mount board sizes, thickness and colour in order to achieve a harmonious result that highlights the artwork without overwhelming it. In the mount board category available at Intermol, a wide range of boards, finishes and thicknesses is offered, allowing each framing project to be tailored to specific requirements.
How to accurately measure the artwork before framing
To ensure the correct mount board selection, it is essential to begin with a precise measurement of the artwork. The exact dimensions of the visible area to be displayed should be taken. For artworks without a white border, it is necessary to decide whether the mount board should slightly overlap the edges to secure the piece properly, or whether the full image should remain visible. Once the measurements have been taken, the appropriate amount of visual space around the subject should be assessed. This calculation determines the most suitable mount board sizes and helps decide whether a standard format or a larger presentation is more appropriate.
Proportions and visual balance when choosing a mount board
The proportion between the artwork and the mount board largely determines the final visual impact. A border that is too narrow creates a sense of constraint and reduces the presence of the artwork, while an excessively wide border can distract the viewer’s attention. The key is to find a balance that is consistent with the size of the subject, the style of the frame and the type of composition. For medium-sized artworks, a visible border of between three and five centimetres generally works well. Small artworks may require only three centimetres, whereas larger or minimalist compositions often benefit from wider margins. Mount board selection should take into account not only measurements but also the psychological effect of spatial distribution.
How to calculate the inner opening of the mount board
Once the artwork dimensions have been measured, the inner opening of the mount board can be calculated. It is recommended that the opening be between one and one and a half centimetres smaller than the artwork so that it is securely held from the back. For example, if an artwork measures thirty by forty centimetres, the inner opening may be approximately twenty-nine by thirty-nine. This difference prevents visible gaps and ensures a stable mounting. For very delicate works, the opening may be reduced slightly less in order to avoid covering important edge details.
Determining the outer size of the mount board and its relationship with the frame
Defining the outer size of the mount board is the next step. This dimension must match the internal size of the selected frame. If a visible border of five centimetres is required around an artwork measuring thirty by forty centimetres, the outer mount board size will be approximately forty by fifty. When using standard frames, the visible border is often adjusted according to the available size. A forty by fifty frame allows borders of between four and five centimetres, while a fifty by seventy frame enables wider borders without disrupting the overall proportion.
The importance of thickness when choosing a mount board
In addition to the inner and outer dimensions, thickness is a decisive factor. A thicker mount board enhances the sense of depth and adds visual quality to the finished frame. Intermol offers mount board options in 1.4 mm, 2.4 mm, 2.8 mm and 3.5 millimetres, making it possible to adapt the mounting to the frame profile and the desired visual effect. Thinner boards are suitable for frames with limited rebates, while deeper frames or exhibition pieces typically require greater thickness.
Types of mount board sheets and their influence on framing
When choosing a mount board, it is important to be familiar with the available sheet sizes. Intermol supplies sheets measuring 80 x 120 mm, 81.5 x 112 mm and 112 x 163 mm, as well as Jumbo formats suitable for large-scale artworks. These sizes help determine whether the sheet allows the desired final dimensions for both the opening and the visible border. The larger the sheet, the greater the flexibility for applying specific proportions.
How to choose the right mount board colour
The colour of the mount board has a direct impact on the perception of the artwork. Neutral tones are generally the most versatile and provide a clearer visual reading. Off-whites, natural shades, soft greys or beige work well with graphic art, photographs and watercolours. When an artwork features strong colours or high contrast, a slightly warmer or cooler tone may be selected to stabilise the composition. In highly contemporary presentations, dark mount boards are often used to emphasise highlights and mid-tones. The essential principle is that the colour should support the artwork without drawing attention away from it.
How to apply a double mount board
A common technique in professional picture framing is the use of a double mount. A narrower bottom mount creates a fine line of colour beneath the top mount, which forms the main border. This technique adds depth and elegance and is particularly suitable for graphic art, illustration and photography. To achieve a harmonious result, the lower mount usually echoes a tone present within the artwork. It is important that both mounts are perfectly aligned and that the combined thickness is compatible with the frame profile.
Special cases: irregular formats or large dimensions
For panoramic artworks, elongated compositions or non-standard formats, the mount board selection must be adapted to the specific proportions of the piece. A wider border may be required on the sides than at the top or bottom to balance the visual weight. For large-format works, it is advisable to use large mount board sheets to avoid joins and maintain structural rigidity. When dealing with complex formats, precise measurement and accurate adjustment of the opening are essential to preserve visual balance.
How to avoid common mistakes when choosing a mount board
One of the most common mistakes is choosing a mount board that is too narrow, which prevents the artwork from breathing. It is also common to select a colour that competes with the subject or a thickness that is incompatible with the frame. Inaccurate measurements can lead to misalignments that are difficult to correct later. For this reason, it is recommended to measure twice before cutting and to ensure that the selected frame is compatible with the outer dimensions of the mount board.
Advanced recommendations for a professional presentation
To achieve a professional-quality finish, it is essential to assess the artwork as a whole before making the final cut. Increasing or reducing a margin by just one centimetre can significantly affect visual balance. Viewing the artwork from a distance also helps confirm that the proportion between the border, the subject and the frame is visually pleasing. Mount board selection influences the overall reading of the piece and can substantially enhance its perceived value.
The importance of measuring your artwork to choose the right mount board
To successfully choose the right-sized mount board, it is essential to measure the artwork accurately, calculate an inner opening slightly smaller than the subject and define a visible border that is consistent with the proportions. Selecting the appropriate colour, thickness and sheet size ensures a balanced and professional result. Proper mount board selection therefore becomes a key factor in enhancing any artwork and achieving a refined, long-lasting presentation.
