When choosing the size of an embroidered logo, on a shirt it's important to consider factors like where it will be placed the purpose of the shirt and the need for balance and visibility. Typically logos on the chest are 3 to 4 inches wide while those on the full front or back can range from 7 to 12 inches wide. For areas like sleeves, 1 to 3 inches is common. It's crucial to ensure that the logo looks proportional to the garment and maintains its appeal. A really wide logo should have a little height to it or it may look a little unbalanced. Additionally the size of the logo should align with how you plan to use the shirt – whether its, for wear promotional events or casual occasions. It may be helpful to consult with an embroidery provider who can offer tailored recommendations based on your design and requirements.
