The table runs on to the right: 6 more columns after Reach. Scroll it sideways to read them.
The 54 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. A dashed tube is a number the maker left out (est.).
The maker's cockpit

Cockpit and seatpost, in the maker's words · 51 words
The Gan 105 build ships with the handlebar "Jaguar XA Aero Di2" and the stem "Tiger Alu Aero Di2" (the page's COCKPIT section). The page prints no bar width, reach or drop and no stem length or angle, and does not say which width and stem each frame size ships with.
OFFICIAL SOURCE, ARCHIVED: Pinarello's own product page "Gan 105" (https://pinarello.com/global/en/bikes/road/endurance/gan/gan-105) as the Internet Archive captured it on 2021-09-18. Source: html table (Internet Archive snapshot 2021-09-18)
How I read the maker's table
the live site no longer has the Gan. The table has NO size column: Pinarello names a frame size by its seat tube centre-to-centre length in cm, so size_label is the CC column written in cm (CC 440 -> "44", 465 -> "46.5"), as in the other Pinarello files; nothing else is derived. Column mapping, from the legend printed beside the table ("CE: SEAT TUBE CENTER - END, CC: SEAT TUBE CENTER - CENTER, L: TOP TUBE CENTER - CENTER, A[deg]: SEAT TUBE ANGLE, B[deg]: HEADTUBE ANGLE, P: CHAINSTAY, T: HEADTUBE, D: BB DROP, R: FORK RAKE, G: FORK HEIGHT, REACH, STACK"): CE -> seat_tube_length; CC -> size label; L -> top_tube_effective (Pinarello's L is drawn horizontal, as on the other Pinarello pages); A -> seat_tube_angle; B -> head_tube_angle; P -> chainstay; T -> head_tube_length; D -> bb_drop; R -> fork_offset; G (fork height, axle to crown, 367 on every size) not in the schema; REACH; STACK. As printed: the 59.5 row's angles carry a degree sign ("72.40°", "73.40°", read as 72.4 and 73.4); the 59.5 row's CE is 615 against CC 595, where every other row's CE is 5 mm under its CC; reach falls one size up, 386 on the 53 and 384 on the 54. STACK DATUM: not stated, null. Not printed, so null: wheelbase, standover, front centre, trail, stock stem and bar per size, stock tyre width (the tyre line reads "Pirelli P7 black 60 tpi Nylon breaker, Max Tyre Size 25mm (width as measured)"). This page is the rim-brake Gan 105 (Shimano 105 R7000 rim brakes, quick-release wheels); the frame line reads "TorayCa T600 UD, Internal Cable Routing, Italian BB, UCI Approved" and the fork "Gan Onda Fork, Tapered head tube". Pinarello listed the same Gan 105 page under both its road competition and road endurance menus in 2021; the category is road race because the table is the race geometry the Dogma F12 family uses (top tubes and angles within a few tenths of the Prince and the 2023 F). MODEL YEAR: the page prints none; 2021 is the year of the capture and the page's footer ("© 2021 - CICLI PINARELLO SRL").
