Food scales are relatively small and don't take up a lot of room in the kitchen. In fact, I keep mine on the counter with a measuring cup and a set of measuring spoons and I use all of them several times a day.
I found that I used to really underestimate what a serving size was and so, I was eating way more than I should have. Using a scale keeps me on track and honest about how much I'm really eating.
