The most important factor is size and legibility. A chart only serves its purpose if the audience can read and understand it quickly, even from the back of the room. If text is too small or the contrast is poor, people won’t grasp the message in time, which defeats using the chart as a visual aid.

To ensure legibility, use a clean, simple font (preferably sans-serif), keep the text large enough for the audience distance, and choose high-contrast colors for text and background. Avoid clutter—limit the amount of dense text and unnecessary decorative elements that can slow reading or confuse the eye. Check the chart from the viewpoint of someone at the far end of the room to confirm everything is readable, and keep key labels and data visually prominent.

While durability and color choices matter for presentation materials, and overly complex text can hinder understanding, nothing beats a chart that’s easy to read at a glance.
