The table runs on to the right: 6 more columns after Reach. Scroll it sideways to read them.
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.
The maker's cockpit

How I read the maker's table
The rim-brake page https://www.dengfubike.com/products/fm098-frame and the disc page https://www.dengfubike.com/products/fm098-disc-frame carry the IDENTICAL geometry table (rows SIZE, A-K, HB, STEM x 49/52/54/56/58/61cm), so they are one file. COLUMN LEGEND (from the diagram): A = seat tube, from the BB centre along the tube to the top tube junction as drawn (440-550); B = top tube drawn horizontal from the seat tube line to the head tube line (top_tube_effective); C = reach and D = stack, both from the BB centre to the top of the head tube; E = head tube length; F = seat angle (drawn at the BB, rear); G = head angle (drawn at the fork); H = BB drop 70; I = chainstay 405; J = front centre, BB centre to front axle; K = wheelbase. The diagram also prints a fork length of 368.0 (not in the table, not a schema field). Fork offset, standover and trail are NOT published (null). Decimals are the maker's (548.35, 387.16, 544.19, 581.33, 590.59 on 54/56cm). Disc max tyre 700x32C, rim 700x25C. MODEL YEAR: not stated (diagrams uploaded 2019, Shopify v=1567042635); model_year null. Bike Insights lists FM098 2021 (build disc) citing this disc page, and an FM098 2014 version (see cross_check and the report). No Panda Podium, Geometry Geeks or 99 Spokes request was made.
