This Wire Gauge Chart is a quick geometry reference for American Wire Gauge (AWG). Compare nominal bare-conductor diameter in inches and millimeters, then view the calculated circular area for the same row.
Use the Wire Gauge Chart for drawing checks, educational reference, printouts, and measurement context. In AWG, a smaller gauge number represents a larger nominal conductor diameter.
Finished cable dimensions, material, electrical performance, circuit suitability, and installation requirements are outside this Wire Gauge Chart. Confirm the actual product and applicable requirements before any safety-critical work.
This Wire Gauge Chart makes common AWG rows easy to compare. Values below are nominal bare-conductor diameter and calculated area, not an electrical rating or a finished-cable measurement.
A frequently referenced small conductor row; confirm the finished product rather than treating the geometry as a cable specification.
The nominal bare-conductor measurement is shown in both unit systems for direct reference.
Use this row for geometry comparison, drawing context, and printable reference checks.
The numbered AWG scale moves opposite to the diameter: lower gauge numbers have larger nominal conductors.
A Wire Gauge Chart answers a narrow question well: what nominal bare-conductor diameter and calculated area correspond to a named AWG size? It does not identify insulation thickness, strand count, finished outside diameter, current capacity, or approval for a particular installation.

Read this Wire Gauge Chart from the AWG designation to nominal diameter, then calculated area. Keep the reference limited to those geometry fields.
Start with the labeled AWG size. The number is a gauge designation, so compare its published geometry rather than assuming its physical diameter.
Use the diameter column when a drawing, hole, or reference needs the bare-conductor size in millimeters or inches.
Use calculated area only as a geometric cross-section reference. It is derived from the nominal diameter shown in the same row.
For a finished cable or any installation, confirm the manufacturer documentation, applicable standard, and project requirements.
These sample rows show the relationship between the AWG label, nominal diameter, and calculated area without extending the chart into circuit-selection guidance.
This Wire Gauge Chart lists 14 AWG at a nominal 0.064084 in, or 1.628 mm, with a calculated area of 2.081 mm². These values describe a nominal bare conductor.
For 12 AWG, this Wire Gauge Chart lists a nominal 0.080808 in, or 2.053 mm, with a calculated area of 3.309 mm². Verify any finished product separately.
For 10 AWG, the Wire Gauge Chart lists a nominal 0.101897 in, or 2.588 mm, with a calculated area of 5.261 mm². The number does not provide an installation recommendation.
Use these terms before comparing values in the Wire Gauge Chart. They help keep a nominal geometry lookup separate from finished-product or installation decisions.
This Wire Gauge Chart derives its dimensions from the standard AWG geometric relationship. That makes it useful for consistent nominal reference, but not a substitute for product data or electrical design.
The Wire Gauge Chart does not provide ampacity, resistance, voltage-drop calculations, conductor material properties, temperature ratings, code tables, or circuit approval. Those depend on the complete product and its intended use.
Use this Wire Gauge Chart for nominal geometry reference only. For electrical, code-regulated, or safety-critical work, verify the manufacturer documentation, product listing, applicable standard, local requirements, and project-specific design with a qualified professional.
After using the Wire Gauge Chart, these references can help with unit conversion and workshop measurement tasks.
