PowerPoint is widely available and can be used to design posters. As a presentation tool, however, it is not designed for many of the precise layout tasks that are necessary in good poster design. Here are a few tips on making PowerPoint work for your poster design:
Find the Page Setup tool (on Windows, it may be under the "Design" tab on the ribbon; on Mac, it may be under the File menu). For "Slides sized for", select "Custom" and set the size in inches (e.g., 48 inches for the width, 36 inches for the height).
Often you will use text boxes to add and organize elements within your poster. Text boxes should be positioned and sized precisely, instead of letting PowerPoint reshape them based on the text inside.
In addition to the Text Box settings, however, you will likely need to adjust the paragraph settings. Right-click on any text to format the "Paragraph...”

If you will be using images within your content, it is important to know a little bit about image files and how much detail those files need to have.
Image resolution is a measure of the amount of information that can be displayed in different environments. For example, the computer I am using is 1280 pixels across the width of the screen and is about 20" wide. If I have an image, that is 400 pixels wide and I zoom in so that it covers my whole screen, the computer will have to create another 880 pixels. This is why images look blurry when we zoom in too close.
Resolution becomes more of a problem for printing, since people cannot zoom in and out of an image once it has been printed. For printing, you can reduce an image without losing quality, but you should never increase its original size, so the higher the resolution the better.
Color can be used to enhance a presentation, but it should be used sparingly and with caution to the cultural associations of certain colors.
The rule of 3 colors - A super simple tool you can use whenever you are in doubt. You cannot go wrong with it. The rule of 3 colors is simple: pick one primary color. Then, pick two other complementary colors.
