Diamond art painting is a kind of pixel art so you have to keep in mind that the smaller the finished kit, the more pixelated it will be. See the photo below for an example of what the same photo looks like in different sizes to get an idea of what I'm talking about. Of course you should always go as large as you can afford and choose the size that will best fit the type of frame you'd like to display it with. You can also see completed project images on most of the photos on our site so you can decide what size you'd like. Here is an easy to remember skill level guide: Beginner: 30cm x 30cm diamond paintings and below. Intermediate: 60cm x 60cm diamond paintings and below. Expert: Recommend 60cm x 60cm diamond paintings and above but can handle any size.
