Does size matter in the garden?

I’ve started using my raised beds where I can net successfully my strawberries, blueberries, & brassicas, for my raspberries I threw 2 very large nets over my hedge which is about 20ft long, I left a few canes unnetted for the blackbirds and thrushes and this seems to be working out ok. I’m definitely moving to smaller plots for better control. My onions are in a small area sectioned off with a few boarded that I was able to net when I put the sets in and now it’s easier to weed them. The only large area I will have are the raspberry hedge and section of the garden for potatoes.
