Canva is a great tool to create online and printable visual content. You can create posters, flyers, infographics, social graphics, postcards and many other things.
Canva is a free tool, though certain options and graphics require an upgrade. Most projects can be made with the free tools and content provided, and you may also upload your own images and graphics to use in your project.
To create a poster in Canva, choose the Use custom dimensions option, change the dimension settings to inches (in), and set the width and height to the desired size. Canva allows for project sizes up to 52" x 52".
Once you've created your poster, be sure to download it as PDF - Print.
PowerPoint can also be used to create a printable poster. You will need to create a new presentation and set up a custom size. To do this you will need to:
Publisher can also be used to create a poster. To do this you will need to:
Some online tools will save in inches, but some will save in pixels. When working with a larger printable poster size, you will want to make sure that images saved as pixels will be large and good quality for print. To do this you will need to understand the relationship between pixels and images in relation to DPI (dots per inch). Most quality printed items will be at least 300 DPI (many may be 600 or even 1200 DPI).
Let’s say you have created a graph using an online application and you want to save it to import it into your poster project. For this example the graph should measure 10” x 8” at 300 DPI.
To figure out the correct pixels for use in your project, you will multiply the inches by the DPI:
10” x 300 = 3000px
8” x 300 = 2400px
Your image will need to measure 3000px by 2400px.
To calculate these automatically, you can use a free online calculator - Printing and Scanning Resolution DPI / PPI Calculator
You may want to review some samples of research posters and infographics to get a better idea about how best to fuse the data and information pieces with the visual parts.
