To choose the right size, this is important: 1. Do you want the branding mark to fill the logo as completely as possible? The logo can be smaller than the brass branding plate. For example, a logo of 30mm x 30mm can also be placed on a logo of 35 x 35 mm. Please indicate this in the notes of the order. 2. Which ratio suits the logo best? For a rectangular logo, a rectangular branding stamp is the best. For a square logo, a square branding stamp and for a round logo, a round branding stamp. But of course all combinations are possible. So a round logo on a square branding stamp is also possible.
