There is no single standard poster size. Most meetings in Europe and Asia ask for A0 portrait (841 × 1189 mm, 33.1 × 46.8 in), and most North American meetings use landscape boards that take a 48 × 36 in poster or larger. What actually decides your size is the conference's board: print anything that fits it, in the orientation it asks for.
This guide gives the common sizes in both units, explains how to read a board size, and lists the official 2026 rules for ten major meetings, each checked on the conference's own site on 22 September 2026. Every size below links to a free, editable PowerPoint template in exactly that size.

Standard poster sizes
| Size | Inches | Centimetres | Where you meet it | Template |
|---|---|---|---|---|
| A0 portrait | 33.1 × 46.8 | 84.1 × 118.9 | The usual choice in Europe, Japan, Korea, Brazil and Russia | A0 portrait |
| A0 landscape | 46.8 × 33.1 | 118.9 × 84.1 | Landscape boards where height is tight (ICLR's 90 cm limit; EGU, where A0 portrait is 6 mm too tall) | A0 landscape |
| A1 portrait | 23.4 × 33.1 | 59.4 × 84.1 | Workshop posters with a 24 × 36 in maximum | A1 portrait |
| 36 × 48 in portrait | 36 × 48 | 91.4 × 121.9 | US meetings with portrait boards | 36 × 48 in |
| 48 × 36 in landscape | 48 × 36 | 121.9 × 91.4 | The most common US size; fits almost every landscape board | 48 × 36 in |
| 72 × 48 in landscape | 72 × 48 | 182.9 × 121.9 | The full 6 × 4 ft board (SfN); 8 × 4 ft boards. Designed at 50%, print at 200% | 72 × 48 in |
| 72 × 36 in landscape | 72 × 36 | 182.9 × 91.4 | 2:1 posters (ICML, ATS); scales to CVPR's 84 × 42 in. Designed at 50%, print at 200% | 72 × 36 in |
| 90 × 120 cm portrait | 35.4 × 47.2 | 90 × 120 | The usual size at meetings in mainland China and Taiwan | 90 × 120 cm |
| 16:9 e-poster | screen | screen | Virtual posters and poster uploads (for example 5120 × 2880 px) | 16:9 e-poster |
A0 and 36 × 48 in are close but not the same: A0 is about 3 in (7 cm) narrower and 1 in (3 cm) shorter. A poster designed at A0 fits wherever 36 × 48 in fits, but not the other way round.
Why the 72 in templates are half size: PowerPoint cannot make a slide larger than 56 in (142 cm) on either side. Posters wider than that are designed at 50% (36 × 24 in for 72 × 48 in) with the type sized for the printed poster, then printed at 200%. PowerPoint's shapes, charts and text are vector, so they print sharp at double size; place photos at 300–600 dpi at the half-size page so they still reach 150–300 dpi when printed.
Board size is not poster size
Most conferences publish the size of the board (the display surface) rather than a required poster size. The board is a maximum. Three rules cover almost every case:
- Stay inside the board with a margin. Leave about 1–2 in (3–5 cm) on each side for pins and for the board number. A poster exactly the size of the board has no room for either, so print it a few per cent smaller.
- Match the orientation. A landscape board wider than 72 in will hold a portrait A0, but it looks lost. A portrait board 90 cm wide will not hold anything landscape.
- Only a few meetings fix the exact size. CVPR prints every poster at 84 × 42 in, and some societies in China require 90 × 120 cm. When a size is required rather than a maximum, the guidelines say so explicitly.
Portrait or landscape
Follow the board. Landscape boards are standard in North America and at large computing and chemistry meetings; portrait boards are standard in Europe and East Asia. If the guidelines allow either, landscape suits posters built around several result figures side by side, and portrait suits a poster read top to bottom in two or three columns.
Scaling a finished poster to another size keeps the layout but changes the type size in proportion. Scaling is fine between sizes with the same ratio (36 × 48 in and 90 × 120 cm are both 3:4; 72 × 36 in and 84 × 42 in are both 2:1). Between different ratios, start from a template in the right size instead of stretching.
Conference poster requirements (2026)
Each entry gives the edition the rules come from, the official page they were read on, and the template size that fits. Rules change every year, so confirm the page for your own edition before you print.
SfN Neuroscience 2026
- Dedicated page: SfN poster template, sizes and rules
- Meeting: 14–18 November 2026, Washington, D.C.
- Board: 6 ft wide × 4 ft high (72 × 48 in, officially approximated as 1.8 × 1.2 m). The board is landscape, and SfN does not require a specific poster size or orientation as long as the poster fits on the board.
- Practical rules: regular posters stay up for a four-hour session and you attend your assigned hour; set up 15 minutes before the session; pushpins are provided at Abstract Locator Stations. All presenters may upload a virtual poster PDF (under 2 GB).
- Template: 72 × 48 in landscape fills the board at 100%, or we recommend printing it at about 97% (70 × 46.5 in) to leave room for pins. 48 × 36 in landscape fits at 100% with space to spare.

NeurIPS 2026
- Dedicated page: NeurIPS poster template, sizes and rules
- Meeting: 6–12 December 2026 in Sydney, and 9–13 December 2026 in Atlanta and Paris.
- Main conference: landscape required, no larger than 140 cm wide × 90 cm high (55.1 × 35.4 in) across all three locations.
- Workshop posters: portrait required, no larger than 61 cm wide × 85 cm high (24.0 × 33.5 in). Workshop posters must use their assigned board or designated area; taping posters to venue walls is prohibited.
- Template: we recommend A0 landscape (118.9 × 84.1 cm) at 100% for the main conference and A1 portrait (59.4 × 84.1 cm) at 100% for workshops. A 48 × 36 in landscape poster (121.9 × 91.4 cm) exceeds the 90 cm height limit and must be scaled to ≤98% if used; 72 × 48 in cannot be used.

- Workshop posters: no larger than 61 × 91 cm, portrait required.
- Template: A0 landscape (118.9 × 84.1 cm) fits under the height cap; A1 portrait for workshops.

ASCO Annual Meeting
- Dedicated page: ASCO poster template, sizes and rules

ASH Annual Meeting 2026
- Meeting: 12–15 December 2026, New Orleans.

- Practical rules: every presenter must upload both a static image of the poster and a five-minute PowerPoint presentation video to Orchestrate (by 16 November 2026 for ASH onsite printing and hanging; ASH also posts a Conflict of Interest disclosure on the board and prohibits using AI tools to generate original text, slides and posters).
- Template: we recommend 48 × 36 in landscape at 100% first, as 72 × 48 in landscape fills the entire approximate board.

Printing and file checks
- Resolution: place photos and micrographs at 150–300 dpi at final print size. Charts, diagrams and text should stay vector, which PowerPoint does by default for native charts and shapes.
- Export: save a PDF at the exact page size of the template rather than printing from PowerPoint, and open it once at 100% to check fonts and images.
- Type size: body text of about 24–32 pt on an A0 or 48 × 36 in poster reads from 1–2 m away. When you scale a poster, the type scales with it.
- Lead time: order printing at least three to five working days before you travel, and ask for fabric if you are flying.
Frequently asked questions (FAQ)
What is the standard size for a scientific poster?
There is no universal standard. A0 portrait (841 × 1189 mm, 33.1 × 46.8 in) is the most common size in Europe and Asia, and 48 × 36 in landscape is the most common in North America. The conference's board size is what counts, so check the guidelines for your meeting before choosing.
Is A0 bigger than 36 × 48 in?
No. A0 is 33.1 × 46.8 in, so it is about 3 in narrower and 1 in shorter than 36 × 48 in. A poster designed at A0 fits anywhere a 36 × 48 in poster fits, but not the other way round.
Can I resize my poster after designing it?
Yes, if the new size has the same ratio: 36 × 48 in and 90 × 120 cm are both 3:4, and 72 × 36 in scales to 84 × 42 in. Everything, including the type, scales in proportion. For a different ratio, start from a template in the target size so the columns and type are set for it.
What size should an e-poster be?
Use the conference's own spec. For NeurIPS, ICML, ICLR and CVPR, that is a landscape PNG up to 5120 × 2880 px (16:9) and 10 MB. For a slide-based e-poster, use a 16:9 page. AACR also accepts a PDF about 24–36 in wide.
Where can I get a poster template in the right size?
Our research poster templates are free PowerPoint files in every size in this guide, in three layouts and up to four colour schemes, with no sign-up needed. To lay out a poster from your own abstract or PDF instead, use the scientific poster maker. For layout and typography advice, see the research poster design guide.
