How do you render wall art to a client's actual wall size?
The client says "the wall is 2.8 m, we need 240×120". Pick "custom", type width and height, done. Anything from a narrow strip to a long horizontal comes out, and the finished size also changes how fine the surface is drawn, so large pieces read from a distance and small ones hold up close.

Short answer: under "finished size", choose "custom" and type width and height in centimetres. The render comes out in that format. Common sizes are already listed, from 30×40 up to 180×120, grouped into portrait, landscape, square and strip. The finished size does more than set the proportion: it sets how fine the surface is drawn, which is the one thing that makes this category different from bags.
In interior projects the size comes first
With bags you settle the design and then the dimensions. Wall art runs the other way: the client has a wall, then looks for a piece. The sofa wall in a show flat, the double-height wall in a hotel lobby, the narrow strip in a private dining room. The designer hands you the size and proportion, and the piece has to fit the wall.
So at render time the format is a delivery spec and every other attribute yields to it. Within one batch each piece can have its own format; a narrow strip is never cropped into a portrait just to make four tidy tiles.

How to enter it
- Check the listed sizes under "finished size" first: portrait 40×60, 60×90, 120×180; landscape 90×60, 180×120; square 50×50, 100×100; strips 30×90, 60×180, 180×60. If the client's size is there, pick it.
- If not, choose "custom" and type width and height in centimetres, for example 240×120.
- Proportions that are too narrow are stopped at input. The narrowest supported today is 1:3. Type 20×200 and you get a message right away, not a failed render later.

Finished size changes what gets drawn
The same proportion at 60×90 and at 120×180 should not carry the same picture. The tool handles this by size band:
| Longest side | Where it hangs, viewing distance | How the surface is drawn |
|---|---|---|
| up to 60 cm | entrance, sideboard, study; viewed within 1 m | must hold up close: inlay units 5–10 mm, three or four levels of fine texture |
| 60–110 cm | living room or bedroom main wall; 1.5–2 m | inlay units 10–20 mm, about three visual levels |
| 120 cm and up | hotel lobby, double-height wall; 3 m or more | the graphic is enlarged and simplified: units 30–50 mm, two or three main planes across the whole piece |
A big panel drawn with fine, busy texture turns to mush from a distance and costs more per unit up close. Enter 240×120 and the longest side puts it in the large band; the wording the model receives changes accordingly.
After the render
Once the client picks a design, "resize" moves the same design to a different format: 120×180 for the show flat, a 180×60 strip for the sales lobby, one design as a family. The listing-page layout works the same way.
In one sentence
The client gives you the wall size, you type width and height, the render comes out in that format with the surface detail tuned to the finished size. Narrowest is 1:3, and anything narrower is flagged as you type it.
