The 4x12 ortholinear keyboard is an extremely common and beloved layout within the keyboard community. Made popular by Jack's Planck from OLKB, the 4x12 ortholinear layout is possibly the most popular non-stagger layout available. Our 48-key 4x12 Ortho keyboard has hotswap compatibility, and the ortholinear layout is far more ergonomic that staggered keyboards because the keys are all much easier to reach, and all keys are within a single row/column from where your hands usually rest. I highly recommend anyone wanting to try to get into the ergonomic keyboard hobby try a 4x12 ortholinear keyboard.
