The 56cm drawn to scale from the table, with no build on it. Stack and reach run from the bottom bracket to the top of the head tube; every size is solved from those two. One square is 100 mm.

How I read the maker's table
seven numeric sizes 50 to 62 cm. Trek's feed states no model year (null); Bike Insights files it as 2020, the disc Madone before the Gen 7 (trek-madone-gen-7.json). Every printed cell equals the Emonda Gen 3 feed's 50 to 62 cm rows (trek-emonda-gen-3.json), standover included. UNITS: Trek publishes the table in centimetres to one decimal and angles in degrees; every length was multiplied by 10 to give millimetres (Decimal arithmetic, exact, no rounding). Column mapping from Trek's geometryDataHeaders: geometrySeattube -> seat_tube_length, geometryAngleSeattube -> seat_tube_angle, geometryLengthHeadtube -> head_tube_length, geometryAngleHead -> head_tube_angle, geometryEffToptube -> top_tube_effective, geometryBBDrop -> bb_drop, geometryLengthChainstay -> chainstay, geometryOffset -> fork_offset, geometryTrail -> trail, geometryWheelbase -> wheelbase, geometryStandover -> standover, geometryFrameReach -> reach, geometryFrameStack -> stack (Trek's frame stack and reach, so stack_datum head tube top). Saddle rail height ranges for the short and tall seatposts are in the feed but not in the schema. Front centre is not in this feed (null).
