Часто задаваемые вопросы (10)

Ответы на популярные вопросы об этом инструменте.

Rafter length = run / cos(angle), where angle = atan(rise/12) — steeper pitches produce proportionally longer rafters for the same horizontal run.
This calculator computes the structural run length only — add your desired eave overhang length separately before cutting rafter stock.
