This is 3.5x2 inches business card. The font size of contact details is 6.5 pt currently. Personally I feel it is a bit small (I tested it after printing on a normal A4 paper in its actual size). It looked small to me.
Also, the font is Helvetica Neue Light. I don't have any Regular or Normal font for this. So I used Light as it felt okay to me.
Most people (3 out of 4) in my office said it's okay. But doubt arised when I read a few answers on SE which suggested font should be 7, 8 or even 10 pts for better readability.
Given all that, is this font too light and small to read?
