Our nails will run small, and there is a reason for that!
When you take the correct size (let's say Medium), and paint over the nail, the gel will harden and push in the sides of the artificial nail. What might've originally be a size Medium could start leaning into size Small territory. This can happen because of the shaping/filing as well as the painting process of the press-on nails. The larger you go up in size, the C-curve of the nail is less noticeable.
Likewise, the smaller sizes have a more noticeable curve.
Generally speaking, if you have small to average-sized fingers I would recommend S sizes. If you have average to above-average-sized fingers, you may find M to be more suitable. Also with the majority of the nails on Maidens Heart you can file down the sides of the press-on nails to make it fit more snug.
Also, certain designs will run even smaller like our nail set First Love. This is due to the almond shape, the tapered shape requires more filing from the edges. This is when you might notice the sides of your natural nails peaking through.
So, that sums up the guide to measuring and buying the right size for you. Thank you for reading and happy shopping!
