Technical Specification: Browser-Based Powerlifting Squat Depth Analyzer
1. Overview
A client-side, single-file web application designed to help powerlifters visualize and verify squat depth. The tool allows users to upload a photo of a squat, draw reference lines on the hip and knee, and receive immediate visual feedback on whether the hip crease is below the knee.
2. Core Features
- Drag-and-Drop Upload: High-performance file input for images (JPG/PNG).
- Precision Drawing Canvas: HTML5 Canvas implementation allowing users to click and drag to define the hip and knee markers.
- Dynamic Depth Calculation: Real-time geometric comparison of Y-coordinates with automatic line rendering.
- Visual Feedback System: Smart color-coding (Green for depth achieved, Red for high squat) based on relative positioning.
- Export/Snapshot: Ability to download the current canvas view as an image file for personal progress tracking.
- Responsive UI: Fully fluid layout that adjusts to desktop and mobile devices without losing drawing precision.
3. UI/UX Layout
- Header: Minimalist title area with a "Reset" button and "Help" modal trigger.
- Main Interface: A split-layout.
- Left/Top: Canvas area for drawing/image analysis.
- Right/Bottom: Information panel displaying status (e.g., "Depth Achieved" / "Above Parallel") and control buttons (Clear, Save).
- Aesthetic: Clean, "SaaS" style. White background (#FFFFFF), slate-gray text (#374151), vibrant blue primary buttons (#2563eb), and distinct green/red status colors for depth feedback.
4. Technical Architecture & Directives
- Framework: Vanilla JavaScript only. Zero build steps.
- Storage: Absolutely NO
localStorage,sessionStorage, or cookies. The state is maintained in-memory exclusively. - Iframe Compatibility: The app is designed for null-origin, sandboxed iframes. Avoid
alert()orprompt(); use custom<div>based overlays for interactions. - Responsiveness: Use CSS Flexbox/Grid. Ensure the canvas scales to fit the viewport while maintaining aspect ratio, or allows panning/zooming if images are high-resolution.
- Visual Polish: Utilize CSS Transitions for button hover states (0.2s ease). Apply soft, subtle shadows (
box-shadow: 0 4px 6px -1px rgb(0 0 0 / 0.1)) to cards.
5. Development Constraints
- No External Servers: All logic must process in the browser thread (Web Workers can be used if heavy pixel manipulation is required).
- Font: Inter or System Sans-Serif font stack for modern clarity.
- Modals: Custom CSS-based modal for instructions, overlaying the main content.

Frequently Asked Questions
Everything you need to know about using this application.
How do I accurately use this tool to measure squat depth?
To get the most accurate measurement, upload a high-quality side-view photo or screenshot of your squat at its lowest point. Ensure your camera is positioned at hip height and is perfectly level with your squat stance to avoid parallax distortion errors. Once the image is loaded, use the drawing tool to place the first point at your hip crease and the second point at the top of your knee. The application will automatically draw a horizontal comparison line, calculating whether your hip crease is successfully below the top of your knee, providing instant visual feedback.
Does this application save my photos or squat analysis data?
This application operates entirely on the client side within your web browser. We do not maintain any servers, databases, or cloud storage, meaning your uploaded images and analysis data are never transmitted to a server or stored permanently anywhere on the web. Because the tool is fully sandboxed in your browser, all data is purged immediately when you close or refresh the tab. You can safely analyze your form without concerns regarding data privacy, account creation, or external tracking of your lifting footage.
Can I use this for video analysis to check depth over time?
Currently, this tool is designed for precision analysis of static images and screenshots taken from your training videos. For the best results, we recommend taking a screenshot of your squat at the deepest point of the repetition from your recorded video. By focusing on static images, we ensure high-accuracy alignment and avoid the performance issues associated with browser-based video decoding. This approach allows for a clean, professional-grade interface that provides immediate, actionable insights into your lifting form without requiring complex video processing.
Is this squat depth tool accurate enough for competition standards?
This tool is intended as a training aid to help powerlifters develop a better understanding of their squat depth and consistency. It provides a visual guide based on the 'hip crease below knee' standard used in most powerlifting federations, but it should not be considered an official judging tool. Factors such as camera angle, clothing fit, and movement speed can impact the perceived depth of a lift. We recommend using this tool to build consistent awareness of your depth, ensuring you train to a competition-ready standard rather than relying on it as a substitute for certified judge feedback.
