When the SID is 40 inches (102 cm), the actual SID should match the displayed SID within a range of:

Explanation:
Accurate SID (source-to-image distance) indicators are essential because small deviations change magnification and exposure calculations. The tolerance for SID accuracy is typically a percentage of the indicated distance. For a 40-inch SID, the standard tolerance is ±2%. That means the actual SID should be within 0.8 inches of the displayed value (40 inches × 0.02 = 0.8 inches), which is about 2.0 cm. So the acceptable range is 39.2 to 40.8 inches (roughly 99.5 to 103 cm). This is why the correct range is ±0.8 inches (±2.0 cm).
