Look at the end of a piece of PVC pipe. Find the widest point across the opening. Measure from the outside edge of the pipe to the opposite outside edge. This measurement is the outside diameter or “OD” of the pipe.
How do I know what size PVC pipe I have?
If you purchased your PVC pipe from a hardware store, you can use the markings on the side of the pipe to tell you what size you have. It will normally indicate the size in decimal or fraction, close to where the manufacturer’s name is, such as ‘1.25’ (for 1-1/4″) or “3/4” (for 3/4″… obviously).
Is PVC pipe diameter measured inside or outside?
PVC Pipe is identified by the ID (Inside Diameter) and is referred to as a “nominal” size which means “in name only.” However this confuses people and most novices try to use the OD (Outer Diameter) to order parts.
What is the outside diameter of 1/2 inch PVC pipe?

How do you measure the diameter of a pipe?
To find it, measure around the circumference of the pipe with flexible measuring tape. Divide the circumference by pi, or about 3.14159. For example, if the circumference is 12.57 inches (319 mm), you would divide by pi, and get an outside diameter of about 4 inches (100 mm).
How do I know what size pipe I have?
All you need to do is wrap a string or a flexible tape measure around the outside of the pipe. Now, take this measurement and divide it by pi (pi = 3.1415). This calculation is the plumbing pipe’s Outside Diameter that you can use to look up the Nominal Size.
What is the outside diameter of 1.5 inch PVC pipe?
1.5″ PVC pipe sch 40 has a nominal inside diameter of 1.5″ and an outside diameter of 1-7/8″. Thus the socket for 1.5″ fittings is approximately 1-7/8″ in diameter. 1″ PVC pipe schedule 40 has a nominal inside diameter of 1″ and outside diameter of 1-1/4″.
What is the outside diameter of 3/8 inch PVC pipe?

What is the outside diameter of 1/2 inch pipe?
0.84
For example, a 1-1/2″ pipe size actually has an outside diameter of 1.9″ NOT 1.5″.
OD and Nominal Pipe Size.

| 1-1/4″ | 1.66 |
What is the inside diameter of 2 inch pipe?
2.375″
Nominal Pipe Size (NPS) is a North American set of standard sizes for pipe. The term nominal refers to pipe in non-specific terms and identifies the inside diameter with a non-dimensional number. For example, a 2-inch nominal steel pipe consists of a family of steel pipe with a 2.375″ diameter.
How do you find the outside diameter of a pipe?
Measure or calculate the outside circumference of the pipe. Then divide that amount by pi, usually rounded to 3.1415. The result is the outside diameter of the pipe.
How do you find the diameter of a pipe from the circumference?
How do I find the diameter from the circumference?
- Divide the circumference by π, or 3.14 for an estimation.
- And that’s it; you have the circle’s diameter.
What is used to measure the diameter of a small pipe?
The pipe caliper tool will then show you the size of the pipe. Our pipe caliper can be used to measure pipes as small as 1/4″ all the way up to 12″ pipes. This device was designed specifically for mechanical insulators and does not include useless numbers/diameters, just iron and copper pipe sizes!
What size is PVC drain pipe?
The 1.5-inch size is used to capture water that might flow out of a kitchen sink, a bathroom vanity or a tub. The 2-inch pipe is commonly used to drain a shower stall or washing machine, and it may be used as a vertical stack for a kitchen sink. A 3-inch pipe is what’s used in homes to pipe toilets.
What is a outside diameter?
Definition of OUTSIDE DIAMETER:
The outside or outer diameter (OD) is one of the key specifications of rolls of labels; this measurement refers to the diameter of the entire roll of labels in its finished form.
What is the outside diameter of 1/2 inch CPVC pipe?
PVC and CPVC Pipe – Schedule 40
| Nominal Pipe Size | Outside Diameter | Weight(lb/100 ft) |
|---|---|---|
| (inches) | (inches) | CPVC |
| 1/2 | 0.84 | 17 |
| 3/4 | 1.05 | 23 |
| 1 | 1.315 | 34 |
What tool do you use to measure diameter?
Caliper Gauge
Caliper Gauge: is a measuring tool to measure outside/ inside diameter/ thickness etc. It is mainly used with dial indicators.
How do you find the diameter of a circle without the radius?
If you don’t have the radius, divide the circumference of the circle by π to get the diameter. If you don’t have the radius or the circumference, divide the area of the circle by π and then find that number’s square root to get the radius. Then, you can just multiply the radius by 2 to find the circle’s diameter.
How do you find the diameter with the area?
Divide the area (in square units) by Pi (approximately 3.14159). Take the square root of the result (Example: 310.56). This is the radius. Now double the radius to get the diameter (Example: 621.12 meters).
What is the OD of 4 inch drain pipe?
