Michael Tsai, writing about iOS 26:
It reduces the amount of information displayed on screen, and you’ll have to scroll more as a consequence. Look at the Before and After layouts: the Before layout doesn’t need solutions to increase its clarity. You’re just injecting white space everywhere. It’s also ironic that where more space and ‘breathing room’ are actually necessary, the header (“Single Table Row” in the figure) is pushed even nearer to the status bar.
I installed macOS 26 Tahoe on an M1 MacBook Pro and it looked downright horsey to me in the default resolution for this display (1512 x 982). Safari was all chrome. Bumping up to 1800 x 1189 looks much better to my eyes, if a little small.
