# Match Rectilinear Horizontal Framing with Active Sensor Widths — Free

Two camera modes can use different active sensor widths even when their lens labels look close. Match horizontal angle explicitly before describing a multi-camera framing plan as equivalent.

**Free and complete.** This guide is a standalone free tool — no account, no card, anywhere. The only paid option is one optional extra outcome: $4 one-time. Nothing in the free tier is gated.

## Who it's for

Creators comparing camera modes for a framing plan

## What's free

- one complete unwatermarked field-angle card run in the app
- three labeled samples and unlimited article-demo calculations
- complete result text and a user-triggered input-state link

## Optional paid add-on

**$4 one-time.**

- unlimited subsequent field-angle card app calculations after a local convenience signal
- print the field-angle card with visible assumptions and its safety boundary
- CSV of the displayed degrees absolute mismatch and row workings; conditional estimate uses your manual-retyping minutes
- five local reading summaries (headline/count/time), not saved full inputs or cross-device backups
