North American (ANSI & Arch)
ANSI C vs. US Tabloid / Ledger
Comparing 2 standards across 8 specifications. 8 key differences identified.
Comparing:
ANSI C
US Tabloid / Ledger
ANSI C is an engineering paper standard defined by ANSI/ASME Y14.1, measuring 17.0 × 22.0 inches (431.8 × 558.8 mm). Formed by joining two ANSI B (Tabloid) sheets or four ANSI A (Letter) sheets, it is the entry format for mechanical CAD assembly drawings and electrical wiring schematics.
US Tabloid / Ledger (ANSI B) is an ANSI/ASME Y14.1 standard paper size measuring 11.0 × 17.0 inches (279.4 × 431.8 mm). Formed by placing two US Letter sheets side-by-side, it is referred to as 'Tabloid' in portrait orientation (used for newspapers and newsletters) and 'Ledger' in landscape orientation (used for accounting spreadsheets and engineering schematics).
