These 25 decorating measurements will help you get just the right look for your home! Key measurements for living rooms, dining rooms, rugs, lighting, and more!

Have you ever looked at your coffee table and thought it just didn’t look right, but couldn’t figure out why?  Or maybe you were installing a light fixture above your table and weren’t quite sure how high it should hang. 

For example, did you know that coffee tables look best when they are 1″-2″ less than the height of the sofa’s seat cushion?  Or that you should leave 1 1/2″ -2″ of spacing between pictures in an art grouping?

It turns out, that in addition to finding your style and knowing how to pull it all together, there are some key measurements that help keep things looking just right. So here are my favorite decorating measurements for a polished look!

  • Coffee tables should be 1”-2” less than the height of the sofa’s seat cushion

  • If using art above a sofa, fill at least 50%-60% of the 5-foot high space above the sofa

Have you ever wanted to make your windows look bigger? Here are some measurements to tell you what length curtains you need, how high to hang your curtains, what fullness you need, and more!

  • Curtain width should always be at least twice the width of the window for fullness.  For modern rooms, just twice the window’s width or even just 1 ¾ times for a really sleek look (if you’re using multiple panels, purchase an even number of panels that equals at least twice your window’s width for fullness)
  • Extend the curtain rod by at least 6”-8” past the outer edge of the trim on each side of the window
  • Always hang curtains as close to the ceiling line as possible to help elongate the window and add anywhere from 2″-8″ to the length if you want the curtain to have the puddle look
