Pipe Dimensions Chart (Nominal ↔ OD / ID)

Select a standard set to display nominal size, OD, ID, and wall thickness.

Keep the source, standard name, and edition in view, then print or save the same table as a PDF.

No numeric values until a standard is selected
Sticky source bar above the table
One-click print with an A4/Letter switch

What this tool covers

  • Check nominal size, OD, ID, and wall thickness for each standard set.
  • For schedule-based standards, values stay hidden until all required conditions are selected.
  • Filter by nominal size to keep the lookup focused.
  • Print or save a PDF while keeping the source bar visible.

How to use

  1. Select a standard set.
  2. If required, select a schedule.
  3. Optionally filter by nominal size.
  4. Confirm the source, standard name, edition, and condition in the source bar.
  5. Choose a paper size, then print or save a PDF.

Glossary

Nominal size

A designated pipe size name, not always equal to measured dimensions.

OD

Outside Diameter.

ID

Inside Diameter. Displayed from source data or derived as OD−2t.

Wall thickness

Wall thickness.

Schedule

Wall-thickness series. Different schedules change thickness and ID.

Formulas

  • ID (derived mode) = OD − 2 × thickness
  • Displayed values follow each standard's precision rules.

FAQ

Why are values hidden before I choose a standard set?

To avoid reference mistakes. Values appear only after all required conditions are selected.

Is source information included in print output?

Yes. The source bar appears at the top of the printed output.

What does the A4/Letter switch affect?

It sets the print page size through the @page size rule.

Does this tool load data from a server?

No. All standard data is embedded in the HTML and processed in your browser.

Important notes

  • Nominal size may differ from measured dimensions.
  • Always verify tolerances against the original standard text.
  • Derived ID values may differ slightly because of the displayed precision.
  • For final engineering decisions, follow the latest official standard text.
