What is the right size for 4K monitor and the distance from our eyes? I have Skyworth monitor at 27" already. If I set macos resolution at 4K, the default font is too small. My distance with the monitor is around 16,5".

My personal preference is 24" nominal for 4K (a 23.8" 4K display has 185ppi), running at @2x (1080p equivalent), because I keep my monitors a bit further back on my desk than others do. I run a triple Dell P2415Q setup. It was great when I started, but as more websites assume 1080 CSS pixels of width means I want tablet mode, its utility has decayed. Because of that I've gone from 3 vertical to 1 horizontal flanked by 2 vertical. These aren't made anymore, and for years nobody else was making monitors at this density. It seems they've become popular again since COVID, and ViewSonic even released the VP2488-4K this year, complete with Thunderbolt 4 and DCI-P3. Asus's offering at this size & resolution is the PA24US.

Another great option is 22" nominal (a 21.5" 4K display has 204ppi), also running at @2x. This is better if you keep the monitor closer to the keyboard side of your desk, or if your desk is not very deep. These are hard to find, and even when you do they're likely to be a portable monitor. Asus has a page for a PQ22UC but I can't tell if it is no longer available, or no longer sold in the US.
