Just like in the story of Goldilocks and the Three Bears, everything in this lovely dining room is not too big and not too small, but just right. The art is exactly the right size for above the fireplace. The rug is large enough to allow the chairs to be pulled back without going over the edge and still not too large for the room. The dining chandelier is in correct proportion to the dining table as is the centerpiece.
And if you look at the back of the room, you can see that the mirror is just the right size for the wall area and sideboard and that the grouping of candle holders are large enough to be the only accessory on the sideboard.
This avoids Mistake No. 8: Incorrect scale and proportion
The most common places where I see scale and proportion out of whack include:
1. Art that is too small for the wall on which it is placed: Try to cover 2/3 of the available area.
2. Bedside lamps that are too small for the side tables: The bottom of the shade should be about even with or just above your shoulder when seated in bed.
3. Sofas that are way too big for the room: No simple rule of thumb here. If you are having an impossible time placing the sofa, it is likely too large.
4. Accessories that are just too little: Just like the phrase "Go big or go home," a few large accessories will always look better than a cluster of tiny objects.
5. Area rugs that are either too large or too small: There are many ideabooks written on the various considerations here.
Tip: To help you get scale and proportion right, print out several large photos of all your rooms and write down dimensions of existing furnishings and room sizes. Take them with you and shop where there are designers to help you get sizes right. Again, I emphasize providing large photos of your rooms or spaces. Nothing is more useless to a designer than a tiny picture on your cell phone.
