When a map places a label beside a location, the choice may feel obvious: put it above and to the right. But users in this study preferred something different—putting the label directly above. Automatic label placement plays a crucial role in cartography, data visualization, and geographic information systems.

Labels convey essential information about distinct data points, from cities and landmarks to important elements in diagrams and charts. The central idea is to prioritize label positions according to users’ perceptual and cognitive preferences rather than traditional conventions.

It is like arranging signs in a busy building: instead of following an old rule about where signs belong, the arrangement follows where people naturally look first. The goal is more intuitive and accessible map designs that prioritize user experience.

The study introduces Perceptual Position Priority Order, a user-centered prioritization of point-feature label positions that puts user perceptions and preferences ahead of traditional conventions. This prioritization is supported by a global user study involving nearly eight hundred participants from forty-eight countries.

Each area was rendered eight times, placing every label in one of eight positions around its point. The maps used a white background, red points, and corresponding labels, while the study removed patterns and vivid colors from the map background so those other factors would not influence judgments.

This allowed the preferences for label positions to be analyzed separately from rules about overlaps, alignment, font sizes, and colors. The final results showed a statistically significant difference between every pair of label positions.

The results therefore showed a clear preference for label positions in the order given by their scores. The preferred label density threshold was twelve point five percent. That preferred threshold corresponded to a median of one hundred fifty labeled points.

In the comparison study, the user-centered ordering and one other ordering consistently performed better than the other tested orderings. Participants perceived these two orderings significantly better than the other group of orderings.

The comparison study confirmed that participants preferred the top position as the first place in the ordering. The following label positions did not seem essential for perceiving the quality of an ordering. The study found a statistically significant ordering of label positions, but it also found distinct clusters of user preferences, showing that people do not all prioritize positions in exactly the same way.

The study used generic maps to evaluate preferences precisely, but other elements of a map could also influence perception. The study did not account for situations such as placing city labels across state borders or placing coastal city labels toward water. Preferences might vary with a map’s intended use and audience, familiarity with the area, language direction, and ease of information search and overall readability.

Uncontrolled online conditions could also introduce unseen biases. The study suggests that map labels should usually begin above their locations rather than at the traditional top-right. That small change could make maps and other labeled graphics feel more natural to read.
