Sizing is the most common ordering mistake with corflute signs. Order too small and your sign disappears into its surroundings, ignored by the very people you need to reach. Order too large and you’re dealing with something awkward to transport, install, and store, often without any meaningful gain in visibility. Getting the size right is straightforward once you understand what each format is actually suited for.
This guide covers every standard corflute sign size available in Australia, what each one is built for, and how to match dimensions to your specific use case.
Standard Corflute Sign Sizes in Australia
Australian corflute signs follow a combination of ISO paper sizes (the A-series) and industry-standard formats established by the real estate sector. Here are the five standard sizes, with approximate imperial equivalents for reference:
A3 (297×420mm / approx. 11.7×16.5 inches)
A3 is a small format, roughly twice the size of a standard sheet of paper. At this size, corflute functions more like a notice board card than a sign: it works in countertop displays, point-of-sale holders, and indoor environments where someone will be standing directly in front of it.
A3 is not visible from the road. It’s not designed to be. Use it where people are already in your space and you want to direct their attention to something specific.
Best for: Counter displays, indoor point-of-sale, small posters, noticeboard use.
A2 (420×594mm / approx. 16.5×23.4 inches)
A2 steps up to a medium format that starts to carry some presence. It works for small footpath applications where pedestrian traffic passes at close range, retail window inserts, and indoor signage in hallways or near entry points.
From a moving vehicle, A2 is hard to read unless you’re travelling very slowly. Stick to pedestrian environments.
Best for: Small footpath displays, retail interiors, A-frame inserts for pedestrian areas, community noticeboards.
A1 (594×841mm / approx. 23.4×33.1 inches)
A1 is where corflute starts to command attention outdoors. At roughly half a metre wide and nearly a metre tall, an A1 sign is readable from a passing car at low speeds and makes a clear statement in a footpath or entry context.
Real estate agents sometimes use A1 for open home directionals in tight suburban streets where a larger board would be impractical. Retailers use A1 in A-frames for footpath advertising. It’s also the right size for construction site safety notices positioned at eye level.
Best for: Outdoor footpath advertising, retail A-frames, open home directional signs, construction safety notices, event directionals.
600×900mm (approx. 23.6×35.4 inches) – Most Popular
This is the industry standard for outdoor corflute signage in Australia, and it’s not close. The 600×900mm format dominates for one reason: it’s the size that the Australian real estate sector standardised on, and from there it spread to elections, events, retail, and construction.
At 600mm wide and 900mm tall, this format is visible from a moving vehicle at normal urban speeds. It fits standard real estate sign frames and A-frame stands designed for the Australian market. It’s large enough to display an agent’s branding, property address, and contact details without crowding. And at this size, a corflute sign can be carried under one arm and installed by one person on a stake in under two minutes.
If you’re not sure which size to order and your application is outdoor, start here.
Best for: Real estate for sale and for lease boards, open home directionals, election and political campaign signs, retail outdoor promotions, event signage, construction site contractor branding.
900×1200mm (approx. 35.4×47.2 inches)
The largest standard format, 900×1200mm is high-visibility signage. At nearly a metre wide and 1.2 metres tall, it commands attention at distance and suits locations where maximum impact matters: major road intersections, large event entrances, construction site boundary fencing, and development marketing hoardings.
This size is not for suburban footpaths or small retail settings. It’s substantial, takes two people to install comfortably, and requires solid anchor points to resist wind. Used in the right context, it’s the most impactful standard corflute format available.
Best for: Major road and intersection signage, large event entrance displays, construction site identification and development marketing, high-visibility election placements.

| Real estate premium listing | 900×1200mm | Used by some agents for prestige properties |
| Open home directional | A1 or 600×900mm | A1 for tight streets; 600×900mm for main roads |
| Event directional signage | A1 or 600×900mm | Depends on venue scale |

| Election major road placement | 900×1200mm | High traffic intersections and arterials |
Viewing Distance: How Far Can Each Size Be Read?
The readable distance for a corflute sign depends on the size of your text and the contrast of your design, but as a general guide based on standard signage legibility:
- A3 (297×420mm): Readable at up to 2-3 metres. Counter and indoor use only.
- A2 (420×594mm): Readable at up to 4-6 metres. Pedestrian footpath environments.
- A1 (594×841mm): Readable at up to 8-10 metres. Slow-moving vehicle traffic and footpaths.
- 600×900mm: Readable at up to 15 metres. Urban vehicle traffic at normal speeds.
- 900×1200mm: Readable at up to 20-25 metres. Arterial roads, open areas, large venues.
These distances assume adequate text size and good contrast. Dark text on a light background, or vice versa, with a font size appropriate to the sign format.
Custom Sizing
If none of the standard formats suit your application, custom sizing is available. Non-standard dimensions, unusual aspect ratios, or very large format requirements can be quoted on request. Contact Paperlust Printshop for a custom quote.
Thickness and Size: Choosing 3mm vs 5mm
Corflute comes in 3mm and 5mm TEKflute. The choice of thickness is connected to size.
3mm works well for A3, A2, A1, and most 600×900mm applications, particularly for shorter campaigns where the sign will be up for weeks rather than months.
5mm is worth considering for 600×900mm signs in windy or exposed locations, and is strongly recommended for 900×1200mm. At that scale, 3mm corflute can flex and bow noticeably, particularly in the wind. The extra rigidity of 5mm keeps the sign flat, the print readable, and the installation stable over time.
Larger signs also bear more wind load. A 900×1200mm sign in an exposed location acts almost like a sail. 5mm gives you the structural integrity to handle that without the sign bowing out of its frame or off its stakes.
