We sell spatial understanding, not data tables. SizeCompare lets you see exactly how a phone compares to a credit card, whether it fits in your pocket, and how it stacks up against the competition. Every dimension comes from official sources, rendered at true scale.
Frequently Asked Questions
Every device dimension is sourced from official manufacturer Tech Specs pages (Apple, Samsung, etc.) or authoritative databases. Reference objects use international standards like ISO/IEC 7810 for credit cards and ISO 216 for paper sizes. Each entry records its source URL and verification date.
Yes. Both objects in a comparison share the same scale factor, calculated from the larger dimension. We never stretch or distort proportions for visual aesthetics. What you see is the true relative size.
Devices marked "Estimated" use pre-release or leaked information. These dimensions are updated to "Official Confirmed" once the manufacturer publishes final specifications.
You can compare any device with any reference object, or any two devices with each other. Each comparison URL is canonical (category-priority ordered) so there is only one URL per pair.
Yes. All comparison tools are free with no ads, no tracking, and no signup required. Future premium features (high-resolution exports, batch comparisons) are planned but the core experience stays free.
Device data is updated when new models are released or when manufacturers publish revised specifications. Each entry has a data_version field for tracking changes over time.
