PRINTING NOTICE: Poster submissions via our online order form must be received no later than 6am (Central) on a Wednesday. All poster printing takes place on Wednesdays unless there is an emergency which prevents us from being able to print as planned. Check our Twitter (@adrcposters) for the most current printing availability information. Please note that we have a limit of 64 posters that can be printed. You cannot reserve a print slot. Printing is first-submitted first-printed. The last poster submitted will be available by 4pm Wednesday (at the latest). You should always aim to submit your files earlier than the night/early-morning before the 6am Wednesday deadline to avoid situations where we run out of slots overnight. Waiting until the last minute may result in your poster not being able to be printed. Refer to our FAQ for more details and other locations you can print posters.

Our Twitter will be updated throughout the business hours of 7:30am-4pm (Mon-Fri). Any available slots listed on our Twitter feed past 4pm on a Tuesday may not be indicative of available slots for Wednesday printing as posters may have been submitted after hours. WUSM observed holidays and other emergencies may impact our ability to print; however, any outages will be communicated via our Twitter feed as far in advance as possible.

Accepted File Formats

  • Microsoft PowerPoint: PPTX format files ONLY (as of 11/10/21). See PowerPoint section below.
  • *Adobe PDF (High or Press Quality preferred if possible)
  • InDesign & Illustrator: Please export these to a PDF (High or Press Quality)
  • Apple Keynote: Export a PDF at the highest quality setting (Instructions)
  • All Other Formats: Export to a PDF (at High or Press Quality if possible)

*Once you create a PDF, open it and verify the file’s actual dimensions. If you submit an 8.5″ x 11″ PDF for printing and mark the order form to scale it to 36″ or 42″, we will print that file exactly as requested and you will be charged for it!

PowerPoint Files

As of 11/10/21, we can no longer support the printing of the old file .PPT format. This deprecated file format has been replaced by the .PPTX format in Office 2007 (Windows) and Office 2008 (MacOS). We print from a Windows PC or a Mac running PowerPoint for Office 365. While we have been able to support the older format that was replaced 13+ years ago, recent updates to PowerPoint have made compatibility with the .PPT format extremely unreliable. We do not always see what you see in your slide when you submit a poster in the old format.

All poster submissions that submit PowerPoint files must be submitted in the updated .PPTX file format or they will be rejected. You run the risk of your poster not being printed at all if you submit a poster file in the old .PPT format (see Print-Ready Files section below). As a student/staff/faculty with Washington University, you receive multiple licenses for Office 365 for multiple devices (work and personal). To install your free and always-current version of Office 365, refer to these instructions:

Print-Ready Files

All files submitted to the Knight ADRC are considered “print-ready.” This means that we assume you have read all of the information provided regarding poster printing on this website; have properly proofed your file and that you understand how to determine what your poster will look like when printed by using a program’s zoom/magnification function.

We are not responsible for typos or for graphics that appear pixelated when you insert images that are of insufficient resolution for the printed size you request on the order form. Any reprints due to designer error are charged at full cost. Furthermore, when you submit a file for printing, catch an error and then resubmit a new file, your original place in the queue is lost. Your new file will be placed into the queue when the new file was received. Check over your work carefully before submitting it for printing!

We DO NOT have time to verify every detail of your poster or to wait for replies/new files for problems that could have been avoided by reviewing the information provided on this site. We provide all of the tools/instructions so you can determine what your poster will look like when printed. Review the information provided and email with any questions BEFORE the day of printing or submission.

Important Design Guidelines

Thoroughly review all of the information below as it key to understanding how to design a poster that we can print. It also contains information on how to design an effective poster in addition to info on how to predict what your printed poster will look like.

Reading Distance and Font Size:

Reading DistanceMinimum Comfortable
Font Size
1.2 feet (0.35m)8 pointsThis is the typical reading distance for a book. Most people prefer text to be 10, 11, or 12 points at this distance.
2.4 feet
16 pointsThis is the closest comfortable distance for reading a large poster.
5.0 feet
32 pointsIn many settings this is as close as one can get to a poster. Sometimes this is because the poster is roped off, or in other cases, large crowds simply make close approach difficult.
25 feet
160 pointsFor almost any setting, you want a title that can be read from at least this far away.
Table information provided by

Maximum Printable Dimensions:

We carry 36″ and 42″ rolls of media. Therefore, the widest (if portrait) or tallest (if landscape) dimension cannot exceed 42″ when printed. The remaining dimension is typically never a problem for most scientific posters; however, the printer’s limit is capped at 59-feet.

Maximum size dimensions for landscape and portrait posters.

Sizing Tips

  • Always keep in mind that one dimension of your poster cannot exceed 42″ (width:portrait or height:landscape) and be printed with us.
  • If the program you are designing the poster in supports the full size of your intended poster print, you should lay your poster out at the full size.
  • The maximum slide size PowerPoint supports is 56″ x 56″. Therefore, the largest size slide we could print at 100% would be a slide size of 42″ x 56″.
  • If you are creating your poster from scratch and cannot create it at full size (100% scaling), then you should create your poster at half-size. We will proportionally scale it up for you. Make sure any images/graphs/etc are high resolution! See the Quick Tip box below.
  • If you design a poster that isn’t exactly half size or full size, we can proportionally scale whatever size your poster is to fit either the 36″ or 42″ roll media.
  • If your poster does not completely fit either the 36″ or 42″ fabric roll media, you will have a margin that you need to trim. We do not have the capability to trim posters.
  • Always leave a .5″ margin around your poster. Do not place text, logos, images or graphs/charts inside this margin in order to avoid problems.

QUICK TIP: A quick way to get an idea of how your poster will look when printed is to zoom in on it at 200% if your poster is half-size. If images/graphs/logos look blocky and unreadable, increase the resolution of your images. If you plan on submitting a file that is 100% of the final desired printed size, view your poster at 100% zoom to get an idea of how your poster will look printed.

Borderless Printing (Satin Paper Only)

What is a borderless print?

A borderless print is simply when you have a background color for the entire slide that goes to the very edge of each side of the slide. 

Important Borderless Requirements:

  • Your poster must be scaled to fill either the 36″ or 42″ satin, paper media for it to be printed borderless.
  • Fabric posters cannot be printed as borderless. A tiny, white margin will appear around your poster.
  • Always leave a .5″ margin around your poster. Do not place text, logos, images or graphs/charts inside this margin in order to avoid problems. (Example Image)
  • If you place images and text too close to the edge of the poster (within the .5″ margin safe zone), your poster will NOT be printed borderless to avoid clipped text/images.
  • Check your margins if you expect a borderless print, or ask us to look at your file before submitting it for printing.

Working with Images

  • Don’t copy and paste images, graphs, etc. into the poster file if you can possibly avoid this.
  • Screenshots (print screens) and web logos will look horrible when blown up 200%.
  • Always attempt to export images for your poster from their program of origin, and then insert them as images.
  • Image type in terms of quality from best to worst: TIFF, BMP, PNG, JPG, GIF
  • Images at 200-300ppi resolution will work best if we’re scaling you poster up when printing
