Start with the frame shape
Frames are not all the same shape. A 30x40 cm frame suits a 3:4 file, while a 40x60 cm frame suits a 2:3 file. If you force the wrong file into the frame, the print service may crop the artwork or add uneven borders.
If you are buying a frame in Australia, check whether the label uses centimetres, inches or A-series sizing. Then choose the matching digital file.
| Frame or print size | Matching file ratio | Practical note |
| A4, A3 or A2 | ISO-A | Good for common Australian paper and frame families. |
| 20x30 cm or 40x60 cm | 2:3 | Common tall poster shape. |
| 30x40 cm | 3:4 | Balanced portrait shape for single prints or sets. |
| 8x10 in or 16x20 in | 4:5 | Useful for many pre-made inch frames. |
| 11x14 in | 11x14 | Use the specific file if the pack includes it. |
When should you use a mat board?
A mat board can make a smaller print feel more polished in a larger frame. It also gives you some flexibility when the print and frame are close, but not identical, in shape.
For vintage botanical prints, a warm white or cream mat often suits the softer style. For bold cherry prints, a clean white mat or simple black frame can keep the colour sharp.
Planning a simple gallery wall
Keep the frame colour consistent if the artworks already have a lot of colour or detail. For native city prints, a set of three or six can work well in matching timber, white or black frames.
Before hanging, lay the frames on the floor and check the spacing. A consistent gap between frames usually looks more intentional than trying to perfectly centre every artwork by eye.
If you want the spacing checked before you buy hardware, the gallery wall spacing calculator helps compare wall width, frame count, frame width, side margins and gaps.
Common framing mistakes to avoid
- Printing from the low-resolution preview instead of the purchased file.
- Choosing a frame before checking the file ratio.
- Letting the printer auto-crop without checking the preview.
- Using glossy paper in a bright room where glare will be distracting.
- Mixing too many frame colours in a small wall space.
