A head-to-head product or service comparison is one of the most common and most useful radar chart applications — it's also one of the easiest to accidentally build in a way that's misleading rather than genuinely informative. Here's how to do it well.
Every axis needs to apply meaningfully to both products — an axis that only makes sense for one of them (a feature Product A has and Product B fundamentally can't, by design, ever have) doesn't belong on a fair comparison chart; it just guarantees one product wins that axis by default rather than showing a genuine tradeoff. Good candidate axes for most product comparisons: Price/Value, Core Feature Set, Ease of Use, Support/Documentation Quality, Reliability, and Performance — adjust to what's actually relevant to your specific category.
Write down, even briefly, what a 1 and a 10 mean on each axis before you assign any numbers — "Price: 10 = cheapest in category, 1 = most expensive" or "Support: 10 = 24/7 live chat with fast response, 1 = email-only with slow response." Scoring without this step tends to drift toward whichever product you already prefer, since vague criteria leave room for unconscious bias in every individual score.
If Price is scored 1–10 and Features is also scored 1–10, make sure both are measuring "how good is this," not one measuring "how good" and the other measuring a raw, unnormalized number (like a literal feature count) — a raw count doesn't sit on the same meaningful scale as a 1–10 quality judgment. See axes explained for the full reasoning.
In the tool, add one axis row per criterion, add two datasets (one per product), name and color each clearly, and enter your scores. With auto-scale on, the chart fills to your highest score automatically — useful for a quick look; switch to a manual max matching your scoring scale (e.g., 10) if you want the chart's outer ring to represent "the best possible score" rather than just "the highest score either product happened to get," which is a subtly different and often more honest framing for a comparison chart.
A radar chart comparison is a summary of the criteria you chose, scored the way you scored them — it isn't an objective, universal verdict. If you're publishing or sharing the chart, it's worth briefly stating your criteria and scoring basis alongside it (even a one-line caption) so a reader can judge whether your criteria match what matters to them, rather than presenting the polygon as if it settles the question on its own.
Comparing two project-management tools on Price, Ease of Use, Integrations, Reporting, Mobile App (1–10 each): Tool A might score strong on Price and Ease of Use but weak on Reporting; Tool B the reverse. The resulting two overlapping polygons make that tradeoff immediately visible — "cheaper and simpler" vs. "more powerful reporting" — in a way a paragraph of prose comparison takes longer to convey and a plain feature-checklist table doesn't visually emphasize at all.
