When many pins sit close together, a map turns into a blur. Marker clustering groups nearby pins into one numbered circle that splits apart as visitors zoom in. It’s free in MapPress, on Google Maps and OpenStreetMap.
Try it: click a numbered cluster to zoom in on its locations.
How it works
- Automatic grouping. Nearby pins combine into a cluster showing how many locations it holds.
- Zoom to expand. Clicking a cluster zooms in until its pins separate.
- Same-address pins. Pins at exactly the same spot can be split apart (spiderfied) so each one can be clicked.
- Cluster bounds. Optionally show the area a cluster covers when visitors hover over it.
- Stop clustering at a zoom level. Choose the zoom where pins always show individually.
Add it to your site
- Go to MapPress › Settings › Clustering and turn on Enable marker clustering.
- Adjust the options if you like. Every map on your site then clusters automatically.
