Crosswords 17x17 of medium size

A 17x17 grid sits between the small format and the large one, noticeably more words than the small grid, meaning a wider range of thematic clues. Yet you can still get through it in one go, without needing several separate attempts the way larger formats often require. This size works well for a longer than usual lunch break or evening, enough time to take it slow, without the crossword turning into a multi day project.
