Almost every canvas print in Australia is sold in one of about a dozen standard sizes. That is not arbitrary — it is the outcome of three separate physical constraints (press width, stretcher bar geometry, shipping carton dimensions) and one historical convention (the imperial photographic print sizes that everyone is used to thinking in). This guide explains why the standard sizes are what they are, when custom sizes make sense, and how to think about size selection for your specific wall.
The standard Australian canvas sizes
Most Australian canvas catalogues offer some combination of:
| Size (cm) | Aspect ratio | Imperial equivalent | Typical use |
|---|---|---|---|
| 30×20cm | 3:2 | ~12×8″ | Bedside, study, gift size |
| 45×30cm | 3:2 | ~18×12″ | Hallway, small wall |
| 60×40cm | 3:2 | ~24×16″ | Bedroom over bed, smaller statement |
| 75×50cm | 3:2 | ~30×20″ | Living room secondary wall |
| 90×60cm | 3:2 | ~36×24″ | Living room over couch, master bedroom |
| 100×75cm | 4:3 | ~40×30″ | Photo aspect, family portrait |
| 120×80cm | 3:2 | ~48×32″ | Open-plan feature, large bedroom |
| 150×100cm | 3:2 | ~60×40″ | Statement piece, gallery wall |
| 180×120cm | 3:2 | ~72×48″ | Very large statement, commercial spaces |
| 90×30cm | 3:1 | ~36×12″ | Panoramic, mantelpiece, narrow walls |
| 120×40cm | 3:1 | ~48×16″ | Panoramic large |
Why these specific sizes? Three reasons.
Reason 1: Print press width
Large-format inkjet presses come in two dominant widths: 1.1m (44 inch) and 1.6m (64 inch). The press width is the long dimension limit for any canvas produced on it without joining. That sets the upper bound:
- A canvas with a long side of 1.0m or less can fit on either press
- Long side 1.0–1.5m requires the 1.6m press
- Long side over 1.6m requires custom production with joined canvases (rare and expensive)
This is why 150×100cm (long side 1.5m, fits 1.6m press with margin) is a common ceiling for catalogue offerings, and why 180×120cm exists only on printers with a 1.62m+ press width.
Reason 2: Stretcher bar economics
Stretcher bars are milled and stocked in standard lengths — usually 20cm increments from 20cm to 200cm. A canvas size that uses standard lengths costs the printer significantly less than one requiring a custom cut. The 20-30-40-50-60-75-90-100-120-150 cm progression maps directly to those mill lengths.
A 92×64cm canvas (the slightly bigger version of 90×60cm) requires the printer to either cut down standard 100cm bars (10cm waste each, multiplied by tens of thousands of canvases) or special-order 92cm bars (logistics overhead). Either pushes unit cost up roughly 8–15%, which is why custom sizes carry a premium.
Reason 3: Shipping carton standards
Canvas prints ship in cardboard boxes sized to fit the canvas with packaging. Box manufacturers produce standard sizes; custom carton sizes cost more per unit and require minimum order quantities. The standard canvas sizes map to standard box sizes:
- 30×20cm canvas fits in a 35×25×6cm flat-pack box
- 90×60cm canvas fits in a 95×65×8cm box
- 120×80cm canvas fits in a 125×85×10cm box
Each custom canvas dimension breaks the carton standard, adding $5–$15 to shipping cost.
The two dominant aspect ratios — 3:2 and 4:3
Most catalogue canvas sizes are 3:2 ratio. This is the classic 35mm camera aspect ratio (and the modern DSLR/mirrorless full-frame ratio). It evolved as a visual standard because it sits between square (which feels static) and 16:9 widescreen (which feels cinematic). For most wall photography, 3:2 is the natural fit.
4:3 (e.g. 100×75cm) is the smartphone-photo and Micro Four Thirds camera aspect ratio. It is slightly less elongated than 3:2 and matches what most phone cameras capture by default. Our personalised photo canvas guide covers aspect-ratio selection.
1:1 (square) is increasingly available as an option — 50×50cm, 80×80cm, 100×100cm. Suits Instagram-style photography, abstract artworks and contemporary single-image statements.
3:1 (panoramic — 90×30cm, 120×40cm) suits horizontal landscape photography, mantelpiece installations and long narrow walls (above a bed-head, across a kitchen splashback).
How to choose the right size for your wall
The 60–70% rule
A statement canvas should occupy 60–70% of the dominant wall element it sits above. For a 2-seater couch (130cm wide): canvas 80–90cm wide. For a 3-seater couch (200cm wide): canvas 120–150cm wide. For a queen-size bed (152cm wide): canvas 95–110cm wide.
This is not a rigid rule — minimalist style favours slightly smaller; gallery and maximalist styles can push to 80%. But 60–70% is the default that consistently works.
Vertical wall space
Canvas size also has to fit the vertical space available. For a wall with 240cm ceiling, with a couch under it (couch back 80cm above floor), available vertical hanging space is about 240−80−20 (clearance below ceiling) = 140cm. Centre the canvas at 150cm from floor, leave 5cm minimum above the couch — canvas vertical dimension up to about 110cm.
Standing distance
The further viewers stand from the canvas, the larger it should be to remain visually present. Rule of thumb: viewing distance = 2× to 3× canvas longest dimension. For a canvas viewed from 3m away (typical living room couch-to-wall), longest dimension 100–150cm.
When custom sizes are worth the premium
Three legitimate reasons:
- A specific wall alcove or panel that requires a non-standard dimension to fit (between mantel and ceiling; between two windows; in a stairwell).
- Matching an existing photograph aspect ratio that does not align with 3:2 or 4:3 — for example, a panoramic phone capture at 16:9 or 1.85:1.
- Multi-panel installations where each panel needs to be sized for the overall composition rather than for the standard catalogue.
Custom canvas pricing normally adds 10–25% to the closest standard size. Lead time normally adds 2–3 business days. For wall-specific installations the premium is worth it; for borderline aspect-ratio adjustments, the standard catalogue is usually the better call.
What happens if your photo aspect ratio doesn’t match a standard canvas?
Three options, in increasing premium:
- Crop the photo to fit a standard canvas. You lose some image content but pay no premium. Usually fine for landscape photography and most images that have some non-essential margin.
- Border the photo with a white or coloured frame on the canvas to make up the aspect-ratio difference. The image is preserved in full, the canvas remains a standard size. Some printers do this at no premium; others charge a small surcharge.
- Order a custom size canvas matching the photo aspect ratio. Full image, no compromise, 10–25% size premium.
For most personalised orders, option 1 (crop) is the most cost-effective and visually clean. Plan the crop deliberately before upload — see our custom canvas guide.

Frequently Asked Questions
Why are canvas prints sold in specific sizes rather than any dimension?
Three reasons: print presses come in fixed widths (1.1m or 1.6m) that set the upper bound; stretcher bars are milled in 20cm increments, so standard sizes match stock lengths; and shipping cartons are produced in standard sizes that map to common canvas dimensions. Custom sizes are available but normally carry a 10–25% premium.
What is the most popular canvas size in Australia?
90×60cm — comfortably the most-ordered single size. It hits the sweet spot for over-the-couch placement in typical Australian living rooms, prints economically on standard press widths, and ships in a stock carton. 60×40cm runs close behind for bedroom and secondary-room use.
How do I choose canvas size for my specific wall?
Measure the dominant wall element (couch back, bedhead, mantelpiece). The canvas should be 60–70% of that width. Centre the canvas at 145–155cm from the floor for standard 2.4m ceilings. Standing viewing distance should be 2–3× the canvas’s longest dimension.
Can I order a canvas in a size that’s not in the catalogue?
Yes. Most printers offer custom sizes up to their press width (typically 1.5m to 1.62m). Premium is 10–25% over the closest standard size and lead time normally adds 2–3 business days.
What if my photo doesn’t match a standard canvas aspect ratio?
Three options: crop the photo to fit a standard canvas (no premium, lose some image area), add a coloured border on a standard canvas (preserves full image, small or no surcharge), or order a custom-size canvas matching the photo aspect ratio (10–25% premium). For most orders, deliberate cropping is the cleanest approach.
