Bed size?

My beds are 1.5m by 6m long and the paths are .5m wide. If I were to set it out again, I would make the paths closer to a metre, maybe 0.8m, and the beds no more than 1.2m. I cannot quite reach the middle of the beds and the paths are just a little too narrow, especially when the grass hasn't been cut. We've all fallen off them!
I'm on a slope so have endlessly rotting boards just on the down slope sides of the ones that run across the slope. The majority run down the slope so I just have to remember to move soil back upslope when digging.
(Sorry, only do metric )
