Poster printing seems straightforward until you’re staring at a rejected file, a blurry proof, or a finished print that looks nothing like your screen — and your event is in two days. Whether you’re a small business owner promoting a grand opening in Scarborough, an entrepreneur launching a new product, or a local organization spreading the word about a community event, getting your poster right the first time matters. This guide was written by our team at Print Grafix to walk you through everything you need to know before you hit submit on that print order — from sizing and paper stock selection to setting up print-ready files like a pro. And in 2026, with more businesses than ever competing for attention on walls, windows, and bulletin boards, a well-produced poster is still one of the most cost-effective marketing tools you can use.

What Are the Standard Poster Sizes and Which One Should You Choose?

The right poster size depends on viewing distance, display location, and how much content you need to fit. Choosing the wrong size is one of the most common and most avoidable mistakes we see from first-time buyers.

Here’s a practical breakdown of the standard sizes we print most often at our Scarborough studio and where each one typically works best:

A rule of thumb our team always shares with new clients: the farther away your audience is when they first see your poster, the larger it needs to be — and the simpler your design should be. Cramming too much text into a 24×36″ piece that’s being viewed from across a trade show floor is a mistake that costs you impact. Keep it bold, keep it readable, and let the size do the work.

If you’re unsure which size fits your use case, our team in Scarborough is always happy to talk it through before you start designing. A quick conversation at the start saves a costly reprint at the end.

How Do You Choose the Right Paper Stock for Poster Printing?

Paper stock is the single biggest factor that determines how professional your poster feels in person — and yet it’s the choice most first-time buyers skip over entirely. The right stock depends on where your poster will be displayed, how long it needs to last, and what kind of impression you want to make.

Here are the most common paper stocks we use at Print Grafix for poster printing, and what each one is best suited for:

Gloss Paper (Coated)

Gloss-coated paper is the most popular choice for retail and event posters. It produces vivid, saturated colours and crisp image reproduction. The shiny surface catches light, making it ideal for product promotions, event announcements, and any design that relies on strong photography. The trade-off is that under direct lighting, gloss can produce glare, which is something to consider for display cases or brightly lit corridors.

Matte Paper (Coated)

Matte paper has a flat, non-reflective finish that gives posters an upscale, editorial feel. It’s easier to read in bright environments and is frequently chosen for professional presentations, academic posters, and artistic pieces where glare would be distracting. Colours appear slightly softer than on gloss, but detail and text legibility are excellent.

Satin / Silk Paper

Satin sits between gloss and matte — it delivers rich colour reproduction without the strong reflective sheen of a full gloss coat. For many of our clients across the GTA, satin is the go-to compromise: photos look vibrant, text stays readable, and the finish feels premium without being flashy. This is a particularly popular choice for real estate listings, restaurant menus, and service-based business promotions.

Laminated Paper

For posters that need to hold up over time — especially in high-traffic areas or locations where they might get touched frequently — lamination adds a protective layer over the print surface. We offer both gloss and matte lamination options at our Scarborough studio. Lamination also adds rigidity and makes the poster more resistant to moisture, which is especially valuable for semi-outdoor use near doors and windows during Toronto’s unpredictable seasons.

Heavyweight vs. Standard Weight

Paper weight (measured in gsm — grams per square metre) affects durability and how the poster hangs. A standard indoor poster typically uses 100–130 gsm coated stock. For something more premium that holds its shape and feels substantial, 170–200 gsm or higher is the right call. If you’re ordering posters for framing or long-term display, going heavier is always the smarter investment.

“The paper your poster is printed on is part of your brand impression. A flimsy stock on a premium product announcement sends the wrong message before anyone reads a single word.”

Why Does Resolution and Bleed Matter — and How Do You Set It Up Correctly?

Resolution and bleed are the two technical settings that trip up the most first-time buyers — and getting them wrong is the fastest route to a print that looks unprofessional. Here is exactly what they mean and how to set them up before you send your file.

Resolution: Always 300 DPI for Standard Posters

DPI stands for dots per inch — it’s the measurement of how much detail your image contains. A file created at 72 DPI (the standard for screens) will look sharp on your monitor but will print blurry and pixelated. Print-ready files should always be set to 300 DPI at the actual size of your poster. If you’re designing a 24×36″ poster, your canvas should be 24×36″ at 300 DPI — not scaled up from a smaller file after the fact. Scaling a low-resolution file up does not add detail; it only makes the blur bigger.

For very large format printing — think 36×48″ and beyond — 150 DPI at final size is generally acceptable, because those prints are meant to be viewed from a greater distance. Our team handles large format printing Toronto businesses rely on regularly, and we can advise on the right resolution setting for your specific dimensions when you submit your request.

Bleed: The 0.125″ Safety Margin That Protects Your Design

Bleed refers to the extra artwork you extend beyond the trim edge of your document. When a poster is printed and cut to size, there’s a small margin of mechanical variability — even on professional equipment. Without bleed, that slight shift in the cut can leave a thin white border along the edge of your poster where the paper shows through. It’s a telltale sign of an amateur file setup, and it’s completely avoidable.

The industry standard is 0.125 inches (3mm) of bleed on all four sides. If your poster background is solid blue, extend that blue 0.125″ past the trim line on every edge. If you have a full-bleed photo, extend the photo. Do not place any critical text or logos within 0.125″ of the trim edge either — keep your important content within a safe zone that’s at least 0.25″ from the edge to avoid anything getting cut off.

CMYK Colour Mode: The Setting Most People Forget

Printers use CMYK (Cyan, Magenta, Yellow, Black) ink, not RGB (Red, Green, Blue) light. Files designed in RGB mode will have their colours converted at the point of printing, and that conversion can shift your colours significantly — especially vibrant reds, blues, and purples. Always set your document to CMYK mode from the very start of your design process, not as an afterthought before saving. If you’re using Adobe Illustrator, Photoshop, or InDesign, this setting is in your document setup or colour mode menu. If you’re working with a designer through our team, we’ll handle this on your behalf.

What File Formats Should You Send to Your Print Shop?

The best file format for printing is a press-ready PDF — it locks in your fonts, preserves your bleed and colour settings, and is the universal standard that professional print shops expect. Here’s a quick breakdown of what we accept and what to avoid.

PDF (Preferred): Export as PDF/X-1a or PDF/X-4 with bleed marks included. Make sure fonts are embedded or outlined before export. This is the cleanest, most reliable format and what our team in Scarborough requests as the default submission.

AI / EPS (Vector files): If your poster is primarily typography and vector-based graphics — like a clean event announcement — sending the original Adobe Illustrator or EPS file with all fonts outlined is an excellent option. Vector files scale without any loss of quality, which is particularly valuable for large format work.

High-Resolution TIFF or PSD: If your poster is photo-heavy, a flattened TIFF at 300 DPI (or appropriate resolution for large format) at the actual print dimensions is a reliable alternative to PDF. Avoid compressing TIFFs with lossy compression.

What to avoid: JPEG files are generally acceptable only if they were saved at maximum quality from the original source and were never previously compressed. Word documents, PowerPoint files, and PNG files exported from web design tools are almost always too low in resolution or missing critical print settings — we see these frequently and they almost always require file corrections before printing.

If you’re not confident in your file setup, don’t worry — our full-service approach means we review every file that comes through and flag any issues before we run a single print. We’d rather catch a problem upfront than hand you a finished poster that doesn’t reflect your brand properly.

Where to Print Posters in Toronto and the GTA Without the Runaround

Where to print posters in Toronto comes down to three things: quality, turnaround, and whether the person on the other end actually cares about your project. For small businesses and organizations across the GTA, the big-box print chains can feel impersonal — you upload a file, hope for the best, and wait. That’s not how we work.

At Www.Printgrafix.Ca, we’re a local print studio based in Scarborough, ON, and we take a personalized approach to every order — whether it’s a single event poster or a large run of marketing materials. Our team reviews your files, asks the right questions about your display environment and deadline, and produces prints we’re proud to put our name on.

We handle everything from standard 11×17″ indoor posters to large format printing Toronto businesses use for trade shows, retail windows, and outdoor displays. If you need banner printing, signage, or branded materials alongside your poster order, we can consolidate everything into a single project — saving you the time and hassle of coordinating with multiple vendors.

Fast turnaround is something we take seriously. We know that event timelines are tight and marketing windows close fast. Many of our clients across Scarborough and the broader GTA come to us specifically because they need reliable same-week or even rush-order production without sacrificing print quality. When you work with a local studio, you’re not a ticket number in a queue — you’re a client we can actually talk to.

Everything your business needs to show up professionally, under one roof, right here in Scarborough.

Frequently Asked Questions

How do I know if my poster file is print-ready?

A print-ready file meets four criteria: it is set to 300 DPI (or 150 DPI for very large format work) at the actual print dimensions; it includes 0.125″ of bleed on all sides; it is in CMYK colour mode; and it is saved as a press-quality PDF with embedded or outlined fonts. If you’re not sure whether your file checks all these boxes, send it to our team in Scarborough and we’ll review it at no charge before your order goes to press.

What is the difference between large format printing and standard poster printing?

Standard poster printing typically covers sizes up to 24×36″ on traditional paper or card stock using offset or digital presses. Large format printing Toronto businesses use for trade shows, building signage, and event backdrops covers anything wider than 24 inches and is produced on wide-format inkjet printers using specialized media including vinyl, fabric, foam board, and heavy-duty coated papers. Large format prints are designed to be viewed from greater distances and are often used outdoors or in high-visibility commercial settings. We handle both at Print Grafix from our Scarborough studio.

Why do my poster colours look different on screen than in print?

This is the most common complaint we hear from first-time print buyers, and it almost always comes down to colour mode. Screens display colour using RGB light, which can render colours — especially electric blues, vivid reds, and fluorescent tones — that simply cannot be reproduced with physical CMYK inks. Designing in RGB and converting to CMYK at the last moment can cause unexpected colour shifts. The solution is to design in CMYK from the beginning, use a colour profile appropriate for your output device (we can provide this), and request a physical proof before committing to a large print run.

Can I order a small quantity of posters without a large minimum order?

Yes — and this is one of the reasons small businesses across the GTA come to us instead of larger commercial printers. At Print Grafix, we work with clients who need a handful of posters for a local event just as readily as those who need hundreds for a regional campaign. We don’t require enterprise-level contracts or large minimum orders. Whether you need five posters for a Scarborough storefront or fifty for a multi-location promotional push, get in touch with our team and we’ll find the most cost-effective option for your specific run size and timeline.
