The standard left chest logo embroidery size is typically 3 to 3.5 inches wide and 2.5 to 3 inches high, depending on the logo shape and garment style. This size provides a balanced, professional appearance on polos, shirts, hoodies, jackets, and uniforms while keeping the design clear and easy to read. Proper sizing, combined with quality digitizing, ensures sharp details, smooth stitching, and consistent branding across all embroidered apparel.
