I don't have any printer but I could try to print it in a copy shop as a test. I can't do it in the next days though.
Ideally, if they have 17"×11" (ledger/tabloid) paper size, this is probably the best fit, assuming that you'd want to keep the original image aspect ratio of 16/9 and establish equal margins all over. It would print as follows:

printed area: (34.82+1/70) × (19.58+1/70) ≈
34.83 × 19.59 cm
paper (ledger = 17" x 11"):
43.18 × 27.94 cm
margins: 4.17+1/350 ≈
4.17 cm
image: 3840x2160 pixels
image size @ 200 dpi: 48.768 x 27.432 cm (apply reduction of c. 71.43% to fit to the established printed area)
image size @
300 dpi (better): 32.512 x 18.288 cm (apply enlargement of c.
107.14% to fit to the established printed area)
Still assuming you want equal margins and keeping it 16/9, then, on A3, the final result will be less harmonious, and unfortunately too short:

printed area: (28.1+1/70) × (15.8+1/70) ≈
28.11 × 15.81 cm
paper (A3):
42 × 29.7 cm
margins: 6.94+1/350 ≈
6.94 cm
image: 3840x2160 pixels
image size @ 200 dpi: 48.768 x 27.432 cm (apply reduction of c. 57.65% to fit to the established printed area)
image size @
300 dpi (better): 32.512 x 18.288 cm (apply reduction of c.
86.47% to fit to the established printed area)
A larger solution is printing on a 50 × 70 cm paper (if it's possible) and frame it. This is a very common and cheap frame size (check for example Ikea Fiskbo). It would print as follows (unfortunately, with big margins, to keep the aspect ratio and equal margins):
- rsz_megachart_on_framed50x70.png (73.84 KiB) Viewed 1249 times
printed area: (45.7+1/70) × (25.7+1/70) ≈
45.71 × 25.71 cm
paper (50 × 70 cm, framed without passe-partout, viewable area):
69 × 29 cm
margins: 11.64+1/350 ≈
11.64 cm
image: 3840x2160 pixels
image size @
200 dpi (better, probably): 48.768 x 27.432 cm (apply reduction of c.
93.74% to fit to the established printed area)
image size @ 300 dpi: 32.512 x 18.288 cm (apply enlargement of c. 140.61% to fit to the established printed area)
All the images above are just drafts, all at 1:10 scale, for comparison. Anyone can print with the above specifications. Or find better ones, of course.
