Hi. I want to understand what tags will be displayed at what zoom levels. I assume this is a feature of the renderer and I’m interested in the standard map layer.
Can anyone point me to this information? Many thanks in advance.

I think that the only way to find out is to study the source code, which can be found at https://github.com/gravitystorm/openstreetmap-carto
I agree that the source code is the only real way of answering this.
However, you should not be worrying about which features render by scale, and the list of features is likely to vary with time. Also, I believe that, in many cases, it is a combination of tags that matters, not just a single tag.
Ok, many thanks for the replies.
The reason for the question was that on some small shops I’ve added recently, the names of the fast food outlets render at different levels to the grocery stores, and I wondered why.
Thanks again.
For the standard layer, you are probably reading too much into it. Whether or not names appear depends on what other features or labels are in the way, and there is no obvious sign that the algorithm prefers one sort of feature, although I haven’t checked the code to see if there might be. On the other hand, the cycle layer clearly thinks refreshment places are important. It does look like the Humanitarian layer may have a policy to prefer refreshments and medecing over other services.
