How to Make an A2 Poster in PowerPoint, Step by Step

To make an A2 poster in PowerPoint, set the slide to 42 × 59.4 cm (portrait) or 59.4 × 42 cm (landscape), create your design at that size, then export it as a PDF for printing. Set the slide dimensions before adding content so text and images do not need to be rearranged later. You will also need to confirm that your printer or print shop can handle A2 paper.

What You’ll Need

PowerPoint for Microsoft 365 on Windows or Mac.
The poster text, images, logos, and other content you plan to use.
A2 paper or a print shop that accepts A2 PDF files. A2 measures 420 × 594 mm, or about 16.54 × 23.39 inches.
High-resolution image files and the rights to use any images, fonts, or logos in your poster.

Step-by-Step

Start a new presentation. Open PowerPoint and choose Blank Presentation, or open a suitable template. If you use a template, check its existing slide size before designing; many are set to widescreen rather than A2. For the easiest setup, create a new presentation and set the page dimensions before adding text, shapes, or pictures.
Open the custom slide-size settings. In PowerPoint for Microsoft 365 on Windows, select Design > Slide Size > Custom Slide Size. In the dialog, enter a width of 42 cm and a height of 59.4 cm for portrait, or a width of 59.4 cm and a height of 42 cm for landscape. If your dialog uses inches, enter 16.54 × 23.39 inches for portrait or reverse those values for landscape. The dimensions should correspond to A2; do not choose a similarly named screen or widescreen setting.
Choose the orientation and confirm. The width and height determine the orientation, but check the orientation option shown in the dialog as well. Select Portrait for a taller poster or Landscape for a wider one, then select OK. If PowerPoint asks how to scale existing content, choose Ensure Fit to reduce the risk of items being cropped. For a new, empty presentation, there should be no content to scale. On a Mac, use Design > Slide Size > Page Setup or the custom-size option shown in your version, then enter the same dimensions and orientation. The wording can vary slightly between Mac releases.
Check the slide dimensions before designing. Reopen the slide-size dialog if you want to verify the measurements. If the values are reversed, the poster will have the wrong orientation; if they show 13.33 × 7.5 inches, the slide is still widescreen. Keep a note of the chosen orientation, especially if you will later export or print through another computer. A2 is the finished page size, not a requirement to use a particular PowerPoint template.
Plan a clear layout. Decide on the main message and place it where it will be noticed first, usually near the top or center. Arrange supporting information into a few clearly separated sections, with a logical reading order. Leave a margin around the edge so important text and logos are not too close to where a printer may trim or fail to print. A practical starting point is to keep essential content at least 10–15 mm from the page edge; follow a print shop’s specified safe area if it provides one. Use alignment guides and consistent spacing rather than positioning each object by eye.
Add text and establish a type hierarchy. Use a large, concise headline, then smaller section headings and body text. As a starting point for an A2 poster viewed from a short distance, try a headline around 60–100 pt and body text around 24–36 pt, then check the result at its intended viewing distance. These are starting ranges, not rules: a text-heavy research poster may need smaller text, while a poster read from farther away needs larger type and less copy. Select text and use the Home tab to adjust font, size, weight, color, and alignment. Avoid long paragraphs in small type; use short lines, labels, or bullets where they make information quicker to scan.
Insert and size images carefully. Use Insert > Pictures to add images from your computer, then resize them with a corner handle to preserve their proportions. Avoid stretching images by dragging a side handle. For a full-page background, check that it reaches the edges only if the printer can print borderless or the print shop will trim the page; otherwise, a white margin may appear. A raster image intended to fill the entire A2 page at 300 pixels per inch is roughly 4961 × 7016 pixels in portrait orientation. Lower-resolution images can still look acceptable when viewed from farther away, but may appear soft when seen close up. PowerPoint text and shapes generally stay sharp in a PDF; placing a small image and enlarging it does not add detail.
Keep colors and contrast readable. Make text stand out clearly from its background. Check combinations such as colored text on a photograph, where busy areas can make words difficult to read; a solid or lightly shaded text panel can help. Avoid relying on color alone to communicate meaning, since the poster may be printed differently from how it looks on screen. If the work must match a brand or a particular print specification, ask the print provider about color requirements rather than assuming the screen preview will match the final paper exactly.
Review the whole poster at presentation size. Use View > Zoom to inspect details, and also zoom out to see the complete composition. Read every line for spelling, missing information, and awkward line breaks. Confirm that logos and images are not covered by other objects, that text boxes are not clipping words, and that the layout has a clear visual order. If possible, print a smaller proof on ordinary paper to check reading order and color balance; a reduced proof cannot show exactly how fine details will look at A2, but it can reveal layout problems.
Export a PDF for printing. Save the editable presentation first. In Windows, select File > Export > Create PDF/XPS and follow the prompts, or use File > Save As and choose PDF as the file type. On Mac, use File > Save As or File > Export and choose PDF, depending on the version. Open the PDF and confirm that it contains one page at the intended A2 orientation, with no cropped objects or unexpected font substitutions. Send the PDF to the print shop and specify A2, rather than relying on the shop to infer the intended paper size from the design.

Common Mistakes

Designing on a widescreen slide: A poster can look finished on a 16:9 slide but be resized awkwardly or surrounded by blank space when printed on A2. Set the custom dimensions first and check them again before export.

Using text that is too small: Text that seems readable while zoomed in may be hard to read from a standing distance. Prioritize the key message, reduce unnecessary wording, and check a physical proof if legibility is important.

Enlarging low-resolution pictures: A small web image may look pixelated when stretched across a large poster. Use the original, larger image where available, or reduce the image’s printed size.

Putting important details at the edge: Printers may leave a white border or trim the paper. Keep essential content inside a safe margin and ask the print shop about bleed and trim specifications if artwork must run to the edge.

Printing the slide at the wrong scale: Selecting a different paper size or a fit-to-page option can shrink or enlarge the design. Check the PDF page size and confirm the print settings before producing the final copy.

Tips

Write the headline and key information before choosing decorative elements. A poster should communicate its main point quickly, even to someone who does not read every section.
Use a small, consistent set of fonts and colors. Repeating the same heading style, spacing, and alignment makes a poster easier to scan.
Leave open space between sections. Filling every part of the page with text or graphics can make even accurate information difficult to find.
Use PowerPoint’s alignment and distribution controls to line objects up and space them evenly. Select the relevant objects, then look for the alignment options on the Shape Format tab.
Keep an editable PPTX copy as well as the final PDF. The PPTX is useful for revisions; the PDF is usually the more reliable file to send for printing.
Ask the print provider whether it wants a particular PDF standard, color profile, bleed, or crop marks. Do not add crop marks or extend artwork beyond the page unless the provider requests those settings.

Troubleshooting

The slide-size dialog will not accept the measurements: Check whether the fields are using inches or centimeters and enter values in the displayed unit. Use 16.54 × 23.39 inches or 42 × 59.4 cm for portrait. If the dialog shows a maximum-size warning, make sure you are entering A2 dimensions rather than a much larger value or an accidental extra zero.

The poster is cropped after changing its size: If you changed the size after adding content, some items may not fit the new proportions. Choose Ensure Fit when PowerPoint offers the option, then inspect each edge and reposition objects. If the original layout is badly distorted, undo the change if possible or return to the original file, set the A2 size first, and rebuild or rearrange the content.

The exported PDF looks different from the slide: Open the PDF in a separate viewer and inspect it at several zoom levels. If a font has been substituted, use a font available on the computer used for export or ask the print shop about its font requirements. Check that images are present, text boxes are not clipped, and the page orientation and size are correct before sending it.

The print comes out too small or has large margins: Check that the PDF page is A2 and that the printer or print service is set to A2 paper. A standard office printer may not support A2, and many printers cannot print to the paper edge. For a full-size poster, use an A2-capable printer or a print shop; ask whether they will print at actual size and trim the page.

Images look blurry in print: Replace small images with higher-resolution originals, avoid enlarging them, and check the exported PDF at a close zoom. The PDF does not restore detail that was missing from the source image. If a print shop flags image resolution, ask what resolution it recommends for the viewing distance and type of poster.

Frequently Asked Questions

What are the exact dimensions of an A2 poster?
A2 is 420 × 594 mm. That is 42 × 59.4 cm, or approximately 16.54 × 23.39 inches. Use those dimensions in portrait orientation, and reverse the width and height for landscape.

Can PowerPoint make a poster larger than A2?
Yes. PowerPoint supports custom slide dimensions, but very large sizes may run into application limits or print-provider requirements. Confirm the maximum page size and desired file format with the printer before designing a larger poster.

Should I save my poster as a PowerPoint file or a PDF?
Keep the PPTX as your editable working file and export a PDF for printing. The PDF is easier to share as a fixed page, but check it before sending because a PDF cannot correct a low-resolution image or a layout error in the original.

What font size should I use for an A2 poster?
There is no universal size because viewing distance and content vary. A headline around 60–100 pt and body text around 24–36 pt can be a starting point, but test the layout at the expected reading distance and make essential information larger if needed.

Can I print an A2 poster on a regular home printer?
Only if the printer supports A2 paper, which many home printers do not. You can print a smaller proof at home, but use an A2-capable printer or print shop for a full-size result.
