Standard corflute sizes in Australia are 600 x 450mm (60.0 x 45.0 cm, 23.6 x 17.7 in), 600 x 900mm (60.0 x 90.0 cm, 23.6 x 35.4 in), and 900 x 1200mm (90.0 x 120.0 cm, 35.4 x 47.2 in). Choose the larger board when your sign must be read from a greater distance.
| Format | Millimetres | Centimetres | Inches |
|---|---|---|---|
| Small format | 600 x 450 mm | 60.0 x 45.0 cm | 23.6 x 17.7 in |
| Standard board | 600 x 900 mm | 60.0 x 90.0 cm | 23.6 x 35.4 in |
| Large format | 900 x 1200 mm | 90.0 x 120.0 cm | 35.4 x 47.2 in |
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. It also covers thickness selection, viewing distance, installation considerations, and how to think about custom sizing when none of the standard formats fits your situation.
At a Glance
Corflute sign sizing in Australia follows the standard sizes sold by Paperlust: 600 x 450mm, 600 x 900mm and 900 x 1200mm. Pick the right size by viewing distance, not by what looks ‘big enough’ on a desk.
600 x 450mm is the smaller outdoor and retail format; 600 x 900mm is the standard real estate and election board; 900 x 1200mm is for footpath visibility from the road. Order too small and the sign disappears; order too large and it becomes awkward to install and store.
- Smaller format: 600 x 450mm, similar in area to A2 and runs landscape or portrait
- Real estate sale boards: 600 x 900mm standard; 600 x 450mm for tighter placements
- Footpath / roadside: 900 x 1200mm minimum for vehicle-readable
- A-size buyers: A1 buyers should choose 600 x 900mm; A2 buyers should choose 600 x 450mm; A3 is not a standard size on the corflute page
- Quick rule: sign should be at least 1cm tall per metre of viewing distance for legible text
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 x 420mm) is not a standard corflute size
A3 is 297 x 420mm. It is not a standard size on the Paperlust corflute page. If you need an exact A3 corflute sign, it is available as a custom size by quote.
Because A3 is not a standard corflute size, there is no standard A3 option to order for road visibility. For a ready-made smaller corflute sign, choose 600 x 450mm and 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.
600 x 450mm (similar in area to A2)
600 x 450mm is similar in area to A2 and runs landscape or portrait. 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, 600 x 450mm is hard to read unless you are travelling very slowly. Stick to pedestrian environments.
Best for: Small footpath displays, retail interiors, A-frame inserts for pedestrian areas, community noticeboards.
600 x 900mm (slightly larger than A1, and the standard real estate and election board)
600 x 900mm is where corflute starts to command attention outdoors. At roughly 600mm wide and 900mm tall, a 600 x 900mm sign is readable from a passing car at low speeds and makes a clear statement in a footpath or entry context.
Real estate agents use 600 x 450mm for open home directionals in tight suburban streets and 600 x 900mm for standard sale boards. Retailers use 600 x 900mm in A-frames for footpath advertising. It is 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.
600x900mm (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 600x900mm format dominates for one reason: it’s the size that the Australian real estate sector standardized 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. When you need a corflute option for a campaign, our election signs cover polling place and roadside display requirements.
900x1200mm (approx. 35.4×47.2 inches)
The largest standard format, 900 x 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. It is also the top of the size range for construction signs in Australia, which run 600 x 450mm, 600 x 900mm and 900 x 1200mm on 3mm or 5mm corflute.
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.

How to Choose the Right Corflute Sign Size for Your Use
The right size is determined by viewing distance, viewing speed, and message complexity. A footpath sign read by pedestrians can be smaller than a roadside sign read from a moving car. A simple “open” sign can be smaller than a full property listing.
Match size to viewing distance. The standard rule of thumb: text should be at least 1cm tall per metre of viewing distance for comfortable reading. A sign read from 5 metres needs 5cm-tall text minimum; a sign read from 30 metres needs 30cm text. Then size the board to fit that text plus appropriate white space.
Match size to viewing speed. Pedestrians stop and read; drivers do not. A driver passing at 50km/h has roughly 2 seconds to register a sign — your message needs to be readable in that time. Bigger always wins for vehicle-targeted signs.
Match size to message complexity. A simple call-to-action (“OPEN”, “SALE”, “AUCTION SAT”) needs less area than a property listing with photo, price, agent details. As a rule, double the message complexity, double the sign area.
If your use case is event entrances, market stalls, or outdoor retail rather than fixed-board signage, see our teardrop banners range. They ship in 2100mm, 3000mm, and 4200mm heights with pole and base included.
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:
- 600 x 450mm: Readable at up to 6 metres. Pedestrian footpath environments and retail displays.
- 600 x 900mm: Readable at up to 15 metres. Urban vehicle traffic at normal speeds.
- 900 x 1200mm: Readable at up to 25 metres. Arterial roads, open areas, large venues.
- A1 buyers: choose 600 x 900mm, which is slightly larger than A1.
- A2 buyers: choose 600 x 450mm, which is similar in area and runs landscape or portrait.
- A3 buyers: A3 is not a standard corflute size; exact A3 signs are available as a custom size by quote.
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.
Minimum Text Size by Sign Format
A useful rule for signage legibility is that text needs to be approximately 10mm tall for every 3 metres of viewing distance. Applying this to standard corflute sizes gives a practical guide: a 600 x 450mm sign viewed at up to 6 metres needs text at least 20mm tall. A 600 x 900mm sign readable from 15 metres needs text of at least 50mm to be legible from the maximum expected distance. For election and real estate signs with a name or headline that needs to register while driving past, the primary text should be at least 80 to 100mm tall, which is why most 600 x 900mm real estate signs use agent names in large, bold type that fills roughly a quarter of the sign height. Secondary information such as a phone number or website can be smaller, since it is only read by people who stop to look more closely.
| Size | Dimensions | Best for |
|---|---|---|
| 600 x 450mm | 600 x 450mm | Small footpath, retail window inserts, indoor and counter signage |
| 600 x 900mm | 600 x 900mm | Real estate and election boards, A-frame inserts, construction safety notices |
| 900 x 1200mm | 900 x 1200mm | Roadside visibility, construction signage, event entrances |
| A1 buyers | choose 600 x 900mm | Slightly larger than A1 |
| A2 buyers | choose 600 x 450mm | Similar in area; runs landscape or portrait |
| A3 buyers | custom size by quote | A3 is 297 x 420mm and not a standard corflute size |
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.
When Custom Sizing Makes Sense
The most common reason to order a custom size is to fit an existing frame or holder. If you’re replacing corflute inserts in a reusable sign system, fence banner holder, or branded display unit, you need the sign to match the holder exactly – standard sizes may not fit. Custom sizing is also useful for development marketing hoardings, where the available space on a hoarding fence may not correspond to any standard sign dimension, and for large construction site identification signs where the span between posts determines the sign width. Corflute is cut from large sheets, so custom sizing adds very little complexity to the production process and typically carries no significant premium for straightforward rectangular cuts. Contact Paperlust Print Shop for a custom quote on non-standard dimensions.
Thickness and Size: Choosing 3mm vs 5mm
Corflute signs come in 3mm and 5mm thickness. The choice of thickness is connected to size.
3mm works well for 600 x 450mm, 600 x 900mm and 900 x 1200mm applications, particularly for shorter campaigns where the sign will be up for weeks rather than months.
5mm is worth considering for 600x900mm signs in windy or exposed locations, and is strongly recommended for 900x1200mm. 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 900x1200mm 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.
How Thickness Affects Stake Installation
Standard real estate H-stakes are designed to accommodate both 3mm and 5mm corflute, as the channel width in most stakes is 6-7mm. However, 5mm corflute fits more snugly in the channel and resists lateral movement more effectively – which can matter in windy conditions or on sloped ground where the sign would otherwise shift. For A-frame installations, the frame clamps typically accommodate both thicknesses. If you are ordering a large volume of signs and plan to reuse existing frames or stakes, confirm the channel width before switching between 3mm and 5mm stock. Most standard Australian real estate frames handle both without modification.
Design Tips for Corflute Sign Sizes
Landscape vs. Portrait Orientation
The 600x900mm format is typically ordered in portrait orientation (600mm wide, 900mm tall) for real estate boards, but landscape (900mm wide, 600mm tall) is also used – particularly for directional signs where a horizontal arrow needs space, or for signs mounted in landscape frame systems. If you’re ordering for a specific frame, confirm the orientation the frame requires before designing your artwork. The product pages at Paperlust Print Shop allow you to specify orientation as part of your order.
Bleed and Safe Zone for Corflute Printing
For all corflute sign sizes, set up your artwork with 3mm of bleed on all edges. The bleed ensures that background colours and edge elements extend to the trim line, preventing white borders appearing from slight cutting variation. Keep all critical content: text, logos, contact details, at least 10mm inside the trim edge to create a comfortable safe zone. On smaller formats like 600 x 450mm, this safe zone is proportionally more important because the sign area is smaller and cropped edges are more noticeable. For 900 x 1200mm signs, the trim tolerance has less visual impact, but maintaining the 10mm safe zone is still recommended for professional results.

Quick Sizing Checklist Before You Order
- Confirm viewing distance — measure how far away the sign will be read from
- Calculate minimum text height — 1cm per metre of viewing distance for comfortable reading
- Account for installation environment — outdoor signs need 30–50% more impact than indoor
- Check frame or fixture dimensions if the sign needs to fit an existing setup
- Decide single or double-sided based on whether the sign is approached from both directions
- Confirm thickness, 3mm for standard, 5mm for >600×900mm or wind-exposed
- Order eyelets if fence-mounting; skip them if A-frame or stake-mounting
- Add UV laminate for any sign installed outdoors longer than 6 months
Frequently Asked Questions
What are the standard corflute sign sizes in Australia?
The standard corflute sign sizes are 600 x 450mm, 600 x 900mm and 900 x 1200mm. Of these, 600 x 900mm is by far the most popular because it became the industry standard for real estate signage and then spread across events, elections, construction, and retail promotions. Choosing from these standard sizes tends to be more cost-effective than custom cutting, and frames designed for standard sizes are widely available in Australia.
What size corflute sign is best for a real estate listing?
The industry standard for residential real estate signage in Australia is 600 x 900mm (portrait). This size is visible from the road, compatible with standard real estate sign frames and stakes, and large enough to display agent branding, property address, and contact details clearly. For high-traffic main roads or premium listings, some agencies use 900 x 1200mm for greater visibility. Whatever size you choose, ensure the stake or frame system is rated for the sign weight and expected wind load in the installation location.
Should I use 600 x 900mm or 900 x 1200mm for outdoor corflute signage?
600 x 900mm works well for most outdoor applications where the sign is viewed within 15 metres: event directional signs, construction site notices, and standard real estate and election placements. 900 x 1200mm is better when the sign needs to be read from a vehicle passing at normal urban speeds or placed on major roads and open areas. If you are buying both and the use case is similar, 600 x 900mm is the more versatile choice because it matches the standard real estate and election board size and standard A-frame inserts.
Can I get a custom size corflute sign?
Yes. Corflute is cut from large sheets, so custom dimensions are straightforward for most applications. Custom sizes work well when you need to fit a specific frame, hoarding opening, or branded display system. When ordering custom sizes, provide exact dimensions in millimeters and confirm whether you need bleed allowance included. Custom sizes may have minimum order quantities and slightly longer production times than standard sizes. For ongoing campaigns, standardizing your size streamlines reorders and reduces setup costs over time. See options at corflute sign printing.
How does sign size affect the cost of corflute printing?
Cost scales with material area. Larger signs use more corflute sheet and more ink, so price increases with size. The jump from 600 x 450mm to 600 x 900mm is moderate; the jump to 900 x 1200mm is more significant. Quantity also affects unit price: ordering 50 signs of the same size will cost less per unit than ordering 5. For budget-conscious projects, consider whether a slightly smaller size achieves the same communication goal. Double-sided printing adds cost but can double the visibility of a sign used on a street median or freestanding frame, often making it better value than two separate single-sided signs.
