How to Decorate:
The world of Harry Potter is vast, which can make things feel disarming when you're trying to pick out room décor. Don't be deterred though. When decorating a room, Joy Moyler recommends starting with small details and building up your collection over time. A few Harry Potter themed bookends are easier to fit in with a room than a full bedding set. Even a frame hung above a desk can be on theme. However, if you know what you want, don't let this rule hold you back. If you want to keep a room relatively neutral, a rug decorated with one of the four houses is a great option to incorporate a Harry Potter theme. Rugs come in many sizes, too, so you can customize them to fit an existing space.
Room décor can transform a space but making sure the décor is the right size is vital. This will help to make your room appear spacious and welcoming - even themed bedrooms should be a place where you can chill and feel relaxed. Posters usually range from 18x24 inches up to 27x40 inches. For small bedrooms, smaller posters are best. The more wall space visible, the larger a room can look. Alternatively, if you have a much bigger area to work with, a decal spanning the length of your wall space will instantly create a Harry Potter vibe even in a neutrally decorated room. As for bedding, a blanket or a handful of themed cushions will nod to Harry Potter without being in your face.
Style of Décor:
As stated by Nick Olsen, room décor can be anything from posters and wall decals to bedding and cushions. Because of this, you can make a statement with over-the-top items or stick to a casual style. A themed bedroom is great, but you'll have to commit to the theme with everything from furniture to accessories, meaning it isn't the best idea if you like to change your decor up often. A themed room is also more high maintenance depending on the materials and colors chosen. Bright red bedding in a Gryffindor style may look cool, but it could be difficult to wash and keep looking good over time. In this case, it's best to stick with posters and other small décor items like trinkets.
Harry Potter is for everyone, but some room décor pieces are better suited to children than adults. If you don't want a childish look in your room, look for more abstract pieces, as these will be less obvious than movie posters whilst still nodding to your love for the franchise. A good example of this is a minimalist poster, which Katie Ridder suggests placing above your bed or dresser. A poster will incorporate Harry Potter style into your room but won't look out of place with other furniture and décor. Another excellent option if you want less childish Harry Potter décor is wall decals. You can pick from a wide range of patterns or quotes that will add mystery and magic to any space.
