Page count is really a clarity decision. A one-page biodata is faster to review, while a two-page biodata gives more space for photos, family background, and expectations.
Use One Page for First Introductions
One page works best when the goal is a fast first impression. Keep the essentials visible and avoid squeezing too many details into tiny text.
Use Two Pages When Context Matters
Two pages make sense when the family expects more detail, when photos are important, or when one page starts to feel crowded and hard to scan.
