Pixel drawing in Photo

[21Pilots]

Drawing with the pixel tool, is there a way of resizing the layer while keeping the sharp edge of the pixels?

Sometimes something I drew isn't the correct scale, but resizing it blurs the line

Yes, but must be pixel perfect. This means position, size, or resizing factor. See Transform panel with more decimal places (Preferences) and pixels unit (Document Setup).

Not sure I understand, do you mean the only is to resize the document and work out the exact pixel to page size proportions?

Pixels are integers, we cannot have 1.25 pixel wide objects, they will be 2 pixels wide, one of which will be lighter in colour by a factor of 1/4 (math is probably wrong about the lighter). Short answer is if you enlarge a pixel layer by a non integer amount you will get blurring.
