Cylinder Lateral Surface Area Calculator
Calculate the curved surface area of cylinders or pipes. Includes standard ANSI pipe size lookups for insulation and painting estimates.
About
In industrial settings, a cylinder is rarely just a geometric abstraction—it's usually a pipe, a tank, or a pillar that needs to be coated, insulated, or wrapped. The Cylinder Lateral Surface Area Calculator is designed with this practicality in mind. It calculates the area of the curved surface (L) instantly.
We have integrated a Standard Pipe Size (ANSI/ASME) lookup to assist engineers and insulators. Instead of manually measuring the Outer Diameter (OD) of a 4-inch nominal pipe, simply select the schedule, and the tool autofills the precise dimensions. This is critical for estimating paint coverage (sq ft) or ordering insulation jacketing materials accurately.
Formulas
The lateral surface area L of a cylinder is the area of the rectangle formed when the cylinder is 'unrolled'. It is calculated as the circumference of the base multiplied by the height.
Or, using Diameter d:
