Reversible 19x19 and 9x9

Does anyone know of a place selling a board with a 19x19 grid on one side and a 9x9 on the other? It’d be perfect for playing on myself and introducing friends to the game. I’ve looked around and all I can find are 9x9/13x13 or 13x13/19x19

I’ve never seen a commercially produced 19×19/9×9 either. Probably cause the size difference would have the tiny 9×9 grid floating naked in a sea of wood. Not necessarily the best aesthetic.

There is always the option to make your own…

Though if you go down that road it’s only a couple dollars and a handful of minutes more to have ALL board sizes in whatever reversible combinations you desire. Maybe a 19×19/13×13 on one board, and a 9×9/7×7 on another. Just an idea.

This guy’s tutorial is probably the easiest to follow and make some decent-looking boards on the cheap.

The aesthetic doesn’t really trouble me so much, as the 9x9 would be just for a few introductory games here and there. It’d just be nice to have the option. I kind of figured I was going to have to make my own. I’m fine with cutting and treating the wood, but I’m a little leery of doing the lines myself. I may just pay to have them laser cut.

Laser cut or even printed ink will give you great results for sure. I just had my grid printed for $40, so it’s not super cheap if your goal is to keep costs down.

Otherwise, for 10 bucks at home depot you can get a drywall square and 2.50 more gets you a double-ended sharpie. Fine tip for the lines, extra fine tip for the hoshi points.

I guess wood is cheap so there’s no harm in trying it myself first and shelling out for the laser cut or printing when I inevitably draw the wonkiest lines anyone has ever seen.

Lol just take your time, check the perpendicular edges for squareness, mark all your edge points in advance, and then connect the dots.

You know about the 3 4 5 method for making a perfect 90° angle?

I have also never seen one

GoGameGuru did sell a 19x19 and 9x9 reversible board, but unfortunately it is no longer available.


Just for reference, I found a couple of 19x19 boards with 9x9 on the reverse from a Japanese website recommended on Cosmogo’s twitch page.

Available in plywood and spruce.

Shipping could be expensive though.


Kurokigoishiten seems to have some smaller boards (9x9, 13x13, and 9+13 combo) for sale, but I’m not sure if there is a 9+19 combo available right now.

Although not as nice as wood, it’s possible to fit a 9x9 grid on a typical (A4 or US letter) piece of paper. I made a few 9x9 boards by just printing on card stock.

Here are some printable grids:

You can also use pieces of paper/cardboard to mask off parts of a 19x19 board to make a smaller playing area.
