Short answer: Lying in your primary sleep position, your nose should roughly align with the center of your chest. If it tilts up, the pillow is too high for you; if it tilts down, too low.
Why this is described as "the quickest way to sanity-check fit"
Rather than waiting through the full breaking-in period to judge fit, this test gives an immediate, practical signal worth checking the moment your pillow arrives.
Why this test applies across multiple sleep positions, not just one
Both the side-sleeper and back-sleeper fit sections point back to this same test — a genuinely universal, repeatable check regardless of your specific position.
💡 Worth knowing: if your nose tilts noticeably up or down, that's a direct, immediate signal worth acting on rather than waiting out the full adjustment week.
