Which panoramic grass painting size to choose based on your bed width?
7 min read · by Walensky
GRASSES PAINTING
An empty bedroom wall, two mismatched bedside tables, and that panoramic grass painting ordered a little too quickly from a photo that didn't show the scale. The result: either it floats like a postage stamp above the headboard, or it spills over the electrical outlets. The motif was perfect, though.
The problem is almost never the choice of subject. It's the width calculation that got skipped.
The direct answerFor a 140 cm bed, aim for a panoramic painting between 120 and 150 cm wide (L or XL format). For a 160, allow 150 cm. For a 180-200, move up to 165 to 180 cm, or consider a custom size. The basic rule: the painting's width should cover 60 to 75% of the bed's width, bedside tables included if they are adjacent.- Ideal painting width = 60 to 75% of the bed width (or of the headboard wall).
- The bottom edge of the painting should sit 20 to 30 cm above the mattress.
- For a 200 cm bed, a large 4XL format (225 cm) or a custom size often works better than a standard format that looks too small.
Why painting size changes everything above a bed
A panoramic format naturally stretches the eye horizontally. That is what makes it such a strong ally above a bed: it follows the line of the headboard instead of cutting it off. But this effect only works when the proportions are right.
Too narrow, the painting looks isolated in an ocean of blank wall, and the eye instinctively searches for something to balance it on each side. Too wide, it swallows the bedside tables and feels overloaded, even with a motif as soothing as grasses swaying in the breeze.
A poorly sized panoramic painting isn't immediately obvious. It's the whole room that seems slightly off balance, without anyone knowing why.
The proportion rule to know before you buy
The proportion that works in nine cases out of ten: the painting occupies between 60 and 75% of the bed's width (bed frame included, not just the mattress).
The ideal ratio between bed width and painting width
Measure the actual width of your bed, not the rounded commercial size. A "160" bed is often 160 cm across the frame, but with an upholstered headboard the whole assembly can reach 170 or 180 cm. That is the width that matters, not the mattress label.
Multiply that measurement by 0.6 for the lower bound and by 0.75 for the upper bound. You get a range, not a single figure, which is normal: decorating is not an exact science.
Margin to leave on each side of the headboard
Beyond 75%, the painting nearly touches the edges of the bed visually, and it crushes the composition. Below 60%, it looks lost. Always keep a visible margin, however modest, between the ends of the frame and the edges of the bed.

Discover this paintingWhich format for your bed size
The panoramic formats in the shop start at 120x40 cm and go up to 255x85 cm, with custom sizes possible from 90x30 cm to 290x97 cm. Enough to match each bed width precisely.
Bed 90-140 cm: compact panoramic format
For a single bed (90 cm) or a 140, the L format at 120x40 cm remains the safest base. On a 140, it covers about 85%, a bit high within the range, but it works well if the headboard posts aren't wide enough to overhang. The Golden Grasses on Green Watercolour Background Painting with Luminous Splashes suits this narrower format particularly well, its warm tones bringing warmth to a bedroom corner often colder than the living room.
Bed 160-180 cm: wide panoramic format
This is the comfort zone of the XL format (150x50 cm) and XXL (165x55 cm). On a 160 bed, the XL falls right within the 75% range. On a 180, switch to the XXL or the 3XL (180x60 cm) to avoid ending up too tight.
Bed 200 cm and above: large format or diptych
On a king size 200 cm wide (often more with the headboard), the 4XL at 225x75 cm does more justice to the space than a format that seems too modest and would suddenly look puny. A custom size also becomes a relevant option here, to adjust to the centimetre rather than jumping from one standard format to another.
There is no diptych in the grasses collection: each painting is a unique single panel. For a very large bed, it's better to choose one wide format than to imagine a two-canvas composition that doesn't exist at Walensky.
Hanging height and distance from the headboard
Height is calculated relative to the mattress, not the floor. Leave 20 to 30 cm between the top of the mattress (or the top of the headboard if it is tall) and the bottom edge of the frame.
- Low or absent headboard: allow 25-30 cm above the mattress.
- Tall upholstered headboard: reduce to 15-20 cm above the headboard itself.
- Always check while seated on the bed: the bottom edge of the frame should never fall into your direct line of sight when reading propped against the pillows.
As for depth, paintings printed on acrylic glass or Dibond aluminium are thin and light, mounting hardware included: no extra space needs to be planned for a frame, since they are delivered unframed and ready to hang directly.

Common mistakes to avoid with a panoramic format
The most common mistake: buying "on a whim" without measuring the actual wall. You zoom in on the product photo, think it looks good, and discover the truth once the painting is on the wall.
Other classic pitfalls: choosing a format that's too wide "to be safe", which ends up overlapping wall sconces or neighbouring door frames. Or the opposite: picking an L format for a 200 cm bed to save money, and ending up with a painting that seems to have shrunk in the wash.

What painting size above a 160 bed?
The XL format at 150x50 cm suits perfectly: it covers about 70 to 75% of the width of a 160 bed, within the recommended proportion range.
At what height should you hang a painting above the bed?
Between 20 and 30 cm above the mattress, adjusting according to the headboard height. The idea is to keep the frame out of your line of sight when you're seated against the pillows.
Can you hang a painting that's too wide above the bed?
Yes, and it's a common mistake: beyond 80-85% of the bed's width, the composition looks overloaded and the painting loses visual impact instead of gaining it.
Should the painting be centred on the bed or on the wall?
Always on the bed. If the wall isn't symmetrical relative to the bed, it's the bed that should guide the centring, otherwise the eye perceives a misalignment even without understanding why.
For a headboard that finally has the right proportions
An empty wall doesn't forgive approximation, but it generously rewards a well-made calculation. The right width, a thoughtful height, and this grasses painting that seemed like a simple aesthetic choice becomes the true headboard of the room, the one you gaze at as you fall asleep, never thinking it's too small or too large.
If your bedroom deserves a similar balance with other materials, the panoramic format is also available in a mineral version: the dimensions guide for a panoramic sand painting above the bed explores the same calculations for this more desert-like atmosphere. And to find the exact format suited to your bed among the full range, head to the grasses painting collection.
