EC1-C

I have to reccomend the [BenQ Zowie EC1-C](https://zowie.benq.eu/en-uk/mouse/ec1-c.html#) in size L. I have big hands and this was great for me, perfect fit. OP's hands are definitely bigger but this mouse *should* suffice

Zowie EC1-DW for sure. Your hands are basically the same size as mine. I'm using an EC1-C and it's honestly the best fit I've ever used.

Second this. I got my hands on a cheaper EC1-c and plan on moving to the dw as soon as money is in order. Love how it fills my palm, which is something I have not found with any other mouse.

Ec1-c I have 20x11 hands and it's perfect. In the bigger side

i'd suggest try out a cheap used EC1-C to see whether you like the shape or not. but from what I see yes it looks quite small for you but people have preferences. Although I have 19x10cm hands, i prefer the size of the Maya over the Maya X, even though the latter is targeted for medium to larger hands

Ergo: EC1-C. Fits my hand like a glove and is perfect for palm grip. I also love the soft clicks even though it does add a small amount of travel distance. Looking forward to trying the EC1-DW when the glossy coatings release. Symmetrical: OP1 8K v1. The slimmer design allows me to grab the mouse with my ring and pinky finger being straightened out, which is another technique I use to control my mice. It also has a noticeably more responsive click latency compared to my EC1. Polling rate doesn’t matter to me, but it’s nice knowing that it’s future-proof with 8Khz capability and swappable switches without soldering.
