This compact mirror has a diameter (side to side) of about 2.75 inches (or 3 inches measuring the compact from side to side including the opening button) and 3/8 inches wide. It has two mirrors with magnification of 1x & 3x respectively. ---Unfortunately, I could not get the weight. I have a regular digital weight scale but this item is so light that it could not get its weight. A postal digital balance for envelopes might help to get the weight for lighter items as is this compact mirror.
