The age recommendation is printed on the packaging of each individual set and in the product description. It depends on the specific set, not on the pixel size.
For the XL (Midi) pixels themselves, the recommendation is from 4 years. It is printed on all packaging. We ship individual pixel squares without packaging, because that would just be unnecessary waste.
Everything else below will help you choose.
The two pixel sizes and their second names
Pixelhobby comes in two pixel sizes. Each has two names.
Classic (Mini) is the original pixel, on the market since 2006. One pixel measures 2.5 by 2.5 millimeters and is 3 millimeters high. It is hollow inside and sits on exactly one pin. There are 314 colors.
XL (Midi) has the larger pixels. They measure 5 by 5 millimeters and are 4 millimeters high. One XL (Midi) pixel covers four pins, two by two. There are 36 colors.
If you're searching for Pixelhobby Mini or Pixelhobby Midi, these are the two pixel sizes you mean.
Why the small pixels aren't automatically the harder ones
The usual advice is: small child, big pixel. It's not that simple.
A Classic (Mini) pixel sits on exactly one pin. One to one. An XL (Midi) pixel has to be lined up over four pins. For a child who is only just learning to get a pixel onto the plate at all, one to one is the easier rule.
Other things speak for XL (Midi). The pixels are easier to grab with your fingers. From what we've seen in the shop, they are also easier to take off and place again. For a child who tries things out and then changes their mind, that's the decisive advantage. And 36 colors are easier to keep track of than 314.
With Pixelhobby there's no gluing and no ironing. So you don't need an iron, and no one has to supervise a hot appliance.
How many pixels really have to be placed
This is where it's easy to miscalculate, and it's the most useful point when choosing.
The plate has pins. With Classic (Mini), every pin gets one pixel. With XL (Midi), one pixel covers four pins. So you only place a quarter as many pixels.
The small base plate has 24 by 24 pins. In Classic (Mini) that's 576 pixels. In XL (Midi) it's 144. It measures 6 by 6 centimeters.
A rectangular medallion, i.e. a keychain plate, has 11 by 14 pixels, so 154.
The regular base plate has 40 by 50 pins. In Classic (Mini) that's 2000 pixels. In XL (Midi) it's 500.
For a child, both count together: how many pixels have to be placed and how big they are. That's why a small base plate with XL (Midi) pixels is the easiest way to start. 144 pixels, each one easy to pick up with your fingers, and the plate is full in one afternoon.
What we recommend for getting started
Start with an XL (Midi) Magnet Set. Small base plate, just a few colors, one design. At least 3 pixel squares, i.e. three full color plates, and therefore at least 3 colors. They are always different ones. Afterwards the picture goes up on the fridge.
Only once that goes well is something bigger worth it. The other way around rarely works out.
Let your child place pixels freely
This is our most important recommendation, and you won't find it in any instructions.
Don't force a young child to follow the template for the design. At that age, rules are a problem. If it doesn't work out, the frustration is big, and the disappointment with the whole hobby is even bigger.
The first stage is a different one anyway: the pixels stay on the plate. Period. The colors end up in a colorful jumble, much like you know from fuse beads in kindergarten. Only after that comes sorting. And only after that comes working from a template.
A wild, colorful picture is not a failed picture.
A practical note on this: a set contains the colors in the quantities the included design needs. So if you place freely, you'll run out of a color at some point. That's no problem, because XL (Midi) colors can be bought individually, in a set of five and in a set of sixteen to top up.
In short
The XL (Midi) pixels are labeled from 4 years. The recommendation that applies to a complete set is on the packaging and on the product page.
When choosing, what matters is not age but the number of pixels. A small base plate with XL (Midi) is 144. That's one afternoon. A regular base plate with Classic (Mini) is 2000. That's a project.
And you know your child better than any number on a box.
