Since SoCG 2019 the length of SoCG submissions is measured in lines and not pages (decision by the SC 2018–2020). This document details the rationale underlying this decision and presents detailed guidelines for appropriate line counting.
The LaTeX document class socg-lipics-v2021.cls (latest version: v0.9, 2022-09-19) is a wrapper around the LIPIcs class and counts lines (nearly) perfectly according to the guidelines. This class is currently maintained by Michael Hoffmann.
