Notes
- Round carbon tube stock in the sizes one maker lists, OD and ID exactly as printed in each product title (OD first, ID in brackets). Wall = (OD − ID) / 2. Lengths offered: 1000 mm, most also 2000 mm.
- Pultruded tubes are the small sizes (0.7 to 12 mm OD); roll-wrapped tubes run from 5 to 60 mm OD in plain and woven finish. The same OD can come with two IDs (10 × 8 and 10 × 9, 12 × 10 and 12 × 11, 25 × 22 and 25 × 23): check the ID before designing an insert.
- Nesting: where one tube's nominal ID equals another's OD (6 × 4 in 8 × 6, 8 × 6 in 10 × 8, 10 × 8 in 12 × 10, 12 × 10 in 14 × 12, 14 × 12 in 16 × 14, 16 × 14 in 18 × 16, 18 × 16 in 20 × 18, 20 × 18 in 22 × 20) the pair is line-to-line at nominal size: check the real tolerance before relying on it as a slip fit. Tube tolerances are not on the maker's list pages.
- Files: one 50 mm section per published OD × ID (true size, no clearance) to subtract from a clamp, socket or wing root, or to check a fit.
- The two hexagon pultrusions (14 (12) and 16 (14)) are listed without saying whether the size is across flats or corners, so they have no file.

Questions
What is the ID of an 8 mm carbon tube?
6 mm for the listed 8 mm pultruded and woven tubes (1 mm wall).
Do carbon tubes telescope?
Several pairs are line-to-line at nominal size (e.g. 8 × 6 over 6 × 4); check the actual tolerance before counting on a slip fit.
