Fashion Croquis Proportion Overlay: Build Your Own (2026)

If you’re searching for a fashion croquis proportion overlay, you’re probably tired of eyeballing whether your sketch matches your reference photo’s proportions. Instead of hunting for an app that almost works, you can build your own proportion comparison tool in Auto — one that fits how you actually sketch.

Why build instead of download

Most croquis proportion guides online are static: a printable 9 head fashion croquis proportion system, a fashion figure template proportion guide as a PDF, or a generic croquis proportion drawing tool that assumes everyone works the same way. They’re fine as references, but they don’t let you actually overlay your own sketch on your own photo and check your own proportions against it. Auto skips the search entirely — you describe what you need, and it builds a working tool around your process, not someone else’s.

Building it in Auto: a quick walkthrough

1. Open Auto and describe the problem. Something like: “I want to compare my sketches against photo references so I can check proportions.” Be specific about your workflow — that’s what makes the tool yours.
2. Snap or upload your images. A photo reference, a scan of your sketch, whatever you’re working with in that session.
3. Ask for the features you actually need. A storage area to keep every image you’ve uploaded so you’re not re-uploading each time. A way to select which reference and sketch to compare. A canvas view that overlays both.
4. Refine the controls. If you want to move and scale images with two-finger scroll and pinch gestures, say so — Auto builds it into the interface, not a menu you have to dig through.
5. Let Auto fix its own errors. Sometimes the first build hits a snag. You don’t need to understand the error — just tell Auto something’s broken and paste what you see. It resolves it and rebuilds.

The whole thing takes minutes, and what you end up with is shaped entirely around your sketching process — not a one-size-fits-all app.

How someone built theirs

One Auto user wanted exactly this: a way to check their croquis proportions against photo references. They started simply — asked for a frame that would let them compare sketches to reference photos, with a storage area holding every image they’d uploaded, and the ability to pick a reference and a sketch to overlay in canvas view. They also wanted direct control: select an image, then move and scale it with two-finger scroll and pinch gestures, just like adjusting a photo on a phone.

The first build hit some technical errors — touch event types and a selection component mismatch in the code. Rather than starting over, they just described the errors back to Auto, and it fixed the underlying code without the user needing to touch a line of it.

The result, now used by others as proof of concept, is a frame called Sketch Compare — built specifically for this proportion-checking workflow, not a generic drawing app.

FAQ

Do I need to know how to draw or code to build one of these? No. You need to know what you want the tool to do — Auto handles the building and the fixing.

Can I build something different from Sketch Compare? Yes — that frame is one example. Your version could focus on a different proportion system, different gestures, or different storage needs.

What if my build has errors like the example above? Just describe what went wrong, or paste the error message. Auto reads it and fixes the code directly.

Is this better than a printable proportion guide? A printed guide is static. A tool you build lets you overlay, move, and scale your own images against your own references — tailored to how you actually work.
