You probably know this, but in Google Maps at least, you can use browser zoom (ctrl/cmd +/-) to change the size of labels without zooming into the actual map.
------
Speaking of maps, I got to work a fun zoom project a few years ago: https://map.fieldmuseum.org/
We used https://openlayers.org/ and thought long and hard about how to best handle zooming and variable levels of information density & visual hierarchy. If you zoom all the way out, we just highlight where the building is relative to the surroundings. As you start to zoom in, we start to highlight major exhibitions and entrances. Then as you zoom in more, we start showing recommended paths, smaller exhibitions, etc. The label sizes try to scale up and down at each level, smoothly, in order to balance readability and density.
Eventually you can reach the max zoom level and the labels will just grow bigger and bigger, but the SVGs dynamically shrink so they remain pictograms and not just contextless-lines.
Then if you keep going, you eventually find microscopic easter eggs :)
The code is pretty jank (and abandoned), but it's FOSS vanilla JS/HTML/CSS, and the only dependency is on OpenLayers: https://github.com/arcataroger/openlayers_indoor_map
Project mention: Show HN: Map2Image – Download Beautiful City Maps | news.ycombinator.com | 2024-01-17These maps look great! Reminds me of a project I saw a long time ago [1]. Glad you made this downloadable for everyone who cannot write code.
P.S.: Now, I also have some (birthday) presents ;-)
to measure distances and convert between our parameters I'm using TurfJS, for which binding is even more trivial:

Project mention: Protomaps – A free and open source map of the world | news.ycombinator.com | 2023-10-23(.shp .gpkg ...) | ogr2ogr -> .geojson | tippecanoe -> .pmtiles
for OpenStreetMap data there's planetiler[4], and and openmaptiles[5] styles that work with Maplibre
with those combinations you've got a great start to something you can host for pennies on AWS S3+CloudFront or Cloudflare R2, with an open source data pipeline

Project mention: Phanpy: A minimalistic opinionated Mastodon web client | news.ycombinator.com | 2024-04-14The creator of this (Chee Aun) is quite prolific and creative with their work (https://cheeaun.com/projects/).
They created https://cheeaun.life, a timeline of their life, more than 10 years ago (which looks to be kept up to date), which was my inspiration for markwhen (https://markwhen.com).
