LinkedIn Crossclimb #785 is a 4-letter Crossclimb ladder from FONT to SIZE. Phase one is crossword solving: 5 middle clues yield FOOT, SOOT, SORT, SORE, SIRE. Phase two is ordering; phase three unlocks the combo ends tied by "A two-word phrase for the height of letters in a block of text.".
Middle phase answers: "Body part that goes into a shoe" = FOOT; "Black residue in a fireplace" = SOOT; "Put in order from smallest to largest" = SORT; "Like muscles after a workout" = SORE; "How to address a king" = SIRE.
Ordering phase: the valid middle chain is FOOT → SOOT → SORT → SORE → SIRE. This permutation is the only valid one-letter chain for these answers.
Link FONT → FOOT: N→O at the third letter (FONT → FOOT) (combo-adjacent).
Link FOOT → SOOT: F→S at the first letter (FOOT → SOOT).
Link SOOT → SORT: O→R at the third letter (SOOT → SORT).
Link SORT → SORE: T→E at the fourth letter (SORT → SORE).
Link SORE → SIRE: O→I at the second letter (SORE → SIRE).

Complete ladder: FONT → FOOT → SOOT → SORT → SORE → SIRE → SIZE. The combo clue "A two-word phrase for the height of letters in a block of text." describes both end words together — "FONT" and "SIZE" each differ by one letter from their adjacent middle rungs and satisfy the shared top+bottom prompt. Pattern: unique middle order — Only one middle permutation forms a valid ladder from top to bottom — if ordering feels stuck, recheck a middle answer.
