About this size

Arch B is where architectural drawings start carrying real plan content. Small residential project plans, partial elevations, presentation drawings for student work, and intermediate-scale concept boards all fit Arch B comfortably.

The size also halves cleanly to Arch A, which makes it the natural unit for booklet-style architectural presentations bound from a single Arch B sheet folded in half.

Pro tips

1 Common for small project plans and presentation drawings. The first Arch size that carries real plan content rather than detail callouts.
2 Halves to Arch A for booklet-style architectural presentations. The fold workflow is built into the series.
3 Standard for academic and student architectural work at intermediate scale.
