Solution 1:

I finally got the answer!

Go to the following menu option:

Preferences - Advanced - Windows - Terminal Windows resize smoothly - Yes

Holding Control will temporarily disable snap-to-grid.

Solution 2:

Press "Control" while resizing will let you overcome the resizing limit. But this is still annoying because I have to manually resize after using BetterTouchTool's window snapping.

Solution 3:

I was suffering the same annoyance until today.

Open Preferences > Profiles > Text > Regular Font > Change Font and play with the font Size and/or Vertical Character Spacing. Test your changes by making an adjustment, resizing iTerm, making another adjustment, and rinse/repeat until the window size lands where you want. On my MBPr, using the Monaco font, a Size of 10 and Vertical Spacing of ~1.25 did the trick.

Edit—Another possible solution:

For the Default profile, open Window and set Settings for New Windows > Style to either Bottom of Screen or Top of Screen and Settings for New Windows > Columns to 134.

New iTerm window title bars will be hidden and iTerm will be flush to the menubar but it's not possible to resize or move the window without first dragging out the iTerm tab (mine are bottom alined so you can't see them in the screenshot) at which point the title bar reappears, taking us back to square one.

I was able to use a pre-made Moom preset to move the window into place without the title bar present; that's how in the following screenshot I got iTerm without title bar positioned on the right:

iTerm Flush

Solution 4:

If you set the default height of new windows to something like 999 rows, they fill up the screen vertically. Also uncheck these settings:

  • Appearance > Hide tab bar when there is only one tab
  • General > Adjust window when changing font size

I always use iTerm in full screen. I have set Profiles > Window > Style to Fullscreen and unchecked General > Use Lion-style fullscreen windows (so there's no animations and ⌘H is not disabled). There is a bug where the menu bar is always shown in Resume'd custom full screen windows though.
