Choosing the right size is essential for a clean and professional look, and a left chest logo size chart helps guide you. Most logos work best between 3 to 3.5 inches wide and about 2 to 2.5 inches tall, though simpler text logos can be slightly smaller and more detailed designs may need closer to 4 inches for clarity. The logo is usually placed 7 to 9 inches down from the shoulder seam and around 4 to 6 inches from the center line. By following a left chest logo size chart, you ensure your design looks sharp, balanced, and perfectly positioned on any shirt.
