Viewport Meta Tag Misconfigured or Missing in Cursor Project
Your Cursor-generated web application appears zoomed out, zoomed in, or renders at an unexpected scale on mobile devices. Text might be tiny and unreadable, the page might show excessive whitespace, or users can't zoom in/out. The root cause is a missing, malformed, or incorrectly configured viewport meta tag.
The viewport meta tag is a single line of HTML that controls how mobile browsers render your page. Without it, mobile browsers assume your page is designed for a 980px desktop screen and shrink everything to fit. With incorrect values, you might lock users out of zooming (an accessibility violation) or cause the page to render at the wrong width.
This issue affects every mobile visitor to your site and is often the first thing that needs fixing for any mobile responsiveness improvements to take effect.
Error Messages You Might See
Viewport not set to device-width
Lighthouse: Does not have a <meta name="viewport"> tag with width or initial-scale
Accessibility violation: user-scalable=no prevents zooming
Content wider than screen on mobile
Common Causes
- Viewport tag missing entirely — Cursor generated an HTML file or layout template without the viewport meta tag in the head section
- Zoom disabled with user-scalable=no — Cursor added
user-scalable=noormaximum-scale=1which prevents pinch-to-zoom, violating WCAG accessibility guidelines - Fixed width viewport — The tag uses a fixed pixel width like
width=1024instead ofwidth=device-width, forcing a specific layout width - Multiple viewport tags — Cursor added a viewport tag but one already exists from the framework/template, causing conflicts with the browser using the last one
- initial-scale missing or wrong — Without
initial-scale=1, some browsers may not properly set the viewport width on orientation change
How to Fix It
- Add the correct viewport tag — Place this in your HTML head:
<meta name="viewport" content="width=device-width, initial-scale=1">. This is the recommended configuration for almost all web applications - Remove zoom restrictions — Delete
user-scalable=no,maximum-scale=1, andminimum-scale=1from the viewport tag. Users must be able to zoom for accessibility - Check for duplicate viewport tags — Search your entire HTML output for
name="viewport". If there are multiple, remove all but one and place it correctly in the head - Verify in framework layout files — For React (index.html), Next.js (app/layout.tsx or _document.tsx), or Svelte (app.html), check the root layout file where the viewport tag should live
- Test on real devices — Browser DevTools device simulation doesn't perfectly replicate viewport behavior. Test on actual phones to verify the fix

Jacek Rozanski
Senior PHP/Symfony developer and DevOps engineer with 20+ years of professional experience, running opcode.pl (web development agency, est. 2004).
Day job: I'm the sole backend developer at merketing company where I own and maintain 11 PHP/Symfony microservices on AWS (ECS Fargate, RDS, S3, CloudFront), handle the full CI/CD pipeline (Bitbucket Pipelines, Docker), and manage monitoring with Sentry and CloudWatch. These services handle high request volumes in production every month.
What I bring to AI-built apps:
- I audit and fix security issues (OWASP methodology), performance bottlenecks, and architectural problems in codebases generated by Cursor, Claude Code, Lovable, Bolt, and v0
- I refactor AI-generated prototypes into production-grade applications with proper error handling, testing, and clean architecture (SOLID, DDD, hexagonal architecture)
- I set up the infrastructure AI tools don't touch: AWS hosting, CI/CD pipelines, automated deployments, database optimization, monitoring, and alerting
- I integrate external services: payment providers, email systems, partner APIs, SSO/auth
Tech stack: PHP 8.x, Symfony, React, Next.js, PostgreSQL, MySQL, Docker, AWS (ECS, RDS, S3, SQS/SNS, CloudFront), Terraform, Supabase. I also use AI tools daily (Claude Code, Cursor) in my own workflow, so I understand both the strengths and the gaps in AI-generated code.
Based in Poland (CET timezone). Available for async work and calls during EU/US business hours.
Sage Fulcher
Hey I'm Sage! Im a Boston area software engineer who grew up in South Florida. Ive worked at a ton of cool places like a telehealth kidney care startup that took part in a billion dollar merger (Cricket health/Interwell health), a boutique design agency where I got to work on a ton of exciting startups including a photography education app, a collegiate Esports league and more (Philosophie), a data analytics as a service startup in Cambridge (MA) as well as at Phillips and MIT Lincoln Lab where I designed and developed novel network security visualizations and analytics. I've been writing code and furiously devoted to using computers to make people’s lives easier for about 17 years. My degree is in making computers make pretty lights and sounds. Outside of work I love hip hop, the Celtics, professional wrestling, magic the gathering, photography, drumming, and guitars (both making and playing them)

Cursor ambassador and agentic tooling builder.
I've scaled systems, automated deployments, and built observability tools for AI coding workflows. I specialize in taking vibe-coded apps from broken prototype to production-ready: fixing Supabase auth/RLS, Stripe integrations, deployment pipelines, and cleaning up AI-generated spaghetti.
I build tools in this space (agentprobe, claudebin, micode) and understand both sides: how AI generates code and why it breaks.

Get HelpFrequently Asked Questions
Is it ever okay to disable zooming?
Almost never. WCAG 2.1 Success Criterion 1.4.4 requires that users can zoom to 200%. The only exception might be a full-screen web game, but even then, accessibility guidelines recommend allowing zoom. Some mobile form interactions can be improved without disabling zoom entirely.
What if my framework already handles the viewport tag?
Many frameworks like Next.js, Nuxt, and SvelteKit include a viewport tag in their default templates. Check your framework's documentation and root layout file before adding another one. Having duplicate viewport tags can cause unpredictable behavior.
