Frequently Asked Questions
CHI uses ACM's acmart class with the sigchi-a format option (or sigconf for some tracks). \documentclass[sigchi-a,anonymous,review]{acmart}. There's no separate chi.sty — it's all configured via acmart options. The sigchi-a format gives you HCI's distinctive single-column body with side margin notes.
sigchi-a is the HCI/CHI format: single-column body, wide right margin for figures and notes, distinctive title block. sigconf is the standard two-column conference format. CHI uses sigchi-a; KDD/WWW use sigconf. Always check the specific CHI track's call for papers — some sub-events use sigconf instead.
\documentclass[sigchi-a,anonymous,review]{acmart} sets sigchi-a layout with double-blind anonymous review and reviewer line numbers. For camera-ready, remove anonymous and review: \documentclass[sigchi-a]{acmart}. The single layout choice handles most formatting decisions.
The acmart class is in TeX Live and MiKTeX (no separate download). For CHI-specific examples, the conference page links to a starter .tex file. TypeTeX bundles a CHI 2026 template with acmart pre-configured for sigchi-a + anonymous + review.
CHI Papers: 12 pages plus references (no cap on refs). Note Papers: 4 pages plus refs. Late-Breaking Work: 6 pages. Always check the specific CHI track — limits differ between Papers, Notes, Case Studies, alt.chi, and Late-Breaking Work.
ACM Reference Format with numbered citations [1], [2]. \cite{key} produces [1]. The acmart class auto-loads the bibliography style. Pair with the bundled ACM-Reference-Format.bst for matching format.
Yes. Generate at https://dl.acm.org/ccs and paste into your preamble. Required for ACM submission. Format: \begin{CCSXML}...\end{CCSXML} \ccsdesc[500]{Human-centered computing~User studies}. The [500] is the relevance number (100-500).
sigchi-a uses a wider main column with a narrow right margin reserved for figures, callouts, and notes. Some authors place small figures in the margin (using \marginpar). The body is single-column for readability — HCI papers tend to be more narrative than data-heavy. Distinctive look that says 'CHI paper' immediately.
