When talking about proportion in design, it means understanding the scale of specific elements within the same room or object. Proportion and scale come into play around selecting furniture for a space because you want everything to feel evenly spaced (or proportioned). For instance, if you feel like the proportion of a rug isn't right in a living room, that's probably because it's either way too small (or big) for the room that it's in!
