Tiles are 256x256 pixels; At the outer most zoom level, 0, the entire world can be rendered in a single map tile. Each zoom level doubles in both dimensions, so a single tile is replaced by 4 tiles when zooming in. This means that about 22 zoom levels are sufficient for most practical purposes.

This table illustrates total horizontal and vertical detail via box size. It does not accurately reflect the screen shape (aspect ratio) of these formats, which is always stretched or squeezed to 4:3 or 16:9. Note that this chart illustrates visible resolution, not pixel count, which is why the 1080i box is not as tall as the 1080p box.
If the shape has a Wikidata item and the OpenStreetMap shape relation already has a wikidata tag set to that item's QID, you can embed a map of the shape directly onto a Wikipedia article as external data. Use the {} template, setting the |id= parameter to the QID, such as Q88466277. Normally, changes to the route in OpenStreetMap are reflected ...
