How can I identify the correct belt length and width?

Length: Defined by the Pitch Length (PL), e.g., 5M-1000 means 5mm pitch, 1000mm pitch length (200 teeth). Calculate the required length from your preliminary center distance and pulley teeth, then select the nearest standard length.
Width: Determines the belt's load capacity. Calculate the effective tension and compare it to the rated tension per unit width for your chosen pitch/profile to determine the minimum required width. Round up to the nearest standard width (e.g., 6mm, 10mm, 15mm, 20mm). Wider belts have higher power capacity.
