I'm running a market garden in Mexico. Clients are local restaurants and then individuals who can order from our weekly availability list. Everything we sell has a unit size in order to make it easier for clients. We chose the unit sizes based on reasonable amounts for families. Most are 250g (kale, chard, broccolini) some are 500g like carrots and beets. Herbs we sell in small bundles of 50g and some things like Baby Greens Mixes we sell in bags of 150g. We bunch almost everything as it helps us organize when we pack boxes for delivery: celery, carrots, kale, broccolini, onions, scallions, various herbs, full-sized arugula etc.
