The default CS2 radar is zoomed in too much, keeps you in the centre and spins as you turn. A few console commands fix all of that and give you a much better picture of the map. Paste them into the console (or your autoexec) and adjust to taste.
Map zoom
cl_radar_scale 0.4 – zoom out to see much more of the map. The range is 0.25 (most zoomed out) to 1 (default, most zoomed in).
Radar size on screen
cl_hud_radar_scale 1.15 – makes the whole radar window bigger. The range is 0.8 to 1.3; default is 1.
Stop centring and rotating
cl_radar_always_centered 0 – you are no longer stuck in the middle, so you don't waste radar space near map edges.cl_radar_rotate 0 – north stays at the top, so callouts are easier to read at a glance.
Icon size (console only)
cl_radar_icon_scale_min 1 – player and bomb icon size, from 0.4 to 1.3. Go higher if you play at a low resolution.
Cleaner background
cl_hud_radar_background_alpha 0 – transparent background (default 0.62).cl_hud_radar_blur_background 0 – turns off the blur.cl_hud_radar_map_additive 1 – shows a light version of the map.
Square radar
cl_radar_square_with_scoreboard 1 – the radar turns square (and shows more) when you hold TAB.cl_radar_square_always 1 – square all the time if you prefer.
Example setup to start from
cl_radar_scale 0.4
cl_hud_radar_scale 1.15
cl_radar_always_centered 0
cl_radar_rotate 0
cl_radar_icon_scale_min 1
cl_radar_square_with_scoreboard 1
Most of these are also in Settings → Game → Radar, but the console lets you see each change right away.
