Standard Poster Sizes for Academic & Medical Conferences in the U.S.


Presenting a Poster at a Conference

Presenting a poster at a conference is a great opportunity to share your research, get feedback, and network with peers. Whether you’re a graduate student or a medical professional, knowing the standard poster sizes can help you prepare a clear, visually appealing presentation that fits the venue’s requirements.


🎯 Common Poster Sizes

In the U.S., most academic and medical conferences specify standard poster dimensions. Here are the three most commonly used poster sizes:

Poster Size (inches)Poster Size (cm)OrientationCommon Use

72 x 48122 x 183LandscapeLarge national or international conferences

Standard poster sizes for scientific, medical, and graduate school conferences.

🧭 Orientation: Landscape vs. Portrait

While landscape orientation is more common, especially at medical or scientific conferences, some events may request portrait orientation. Always check the event guidelines.

Tip: If you’re not sure, default to landscape 48 x 36 unless told otherwise.


🖨️ Printing Tips

  • Check your institution’s printing center – many offer academic discounts or free printing.
  • Save your file as a PDF to preserve formatting.
  • Use vector graphics or high-res images (300 DPI) for clarity when printed at large sizes.

✅ Final Checklist

Before you print, make sure to:

  • 🔲 Verify size and orientation required by the conference.
  • 🔲 Leave at least 0.5″ margins on all sides.
  • 🔲 Use fonts that are legible from 3–5 feet away (e.g., 24–32 pt for body text).
  • 🔲 Proofread everything — spelling errors can distract from your message.

💡 Bonus Tip: Practice Your Pitch

Don’t just design the poster — practice explaining it in 2–3 minutes. Most interactions at poster sessions are brief, and a concise, engaging summary will help you stand out.
