How to Determine Your Face Shape from a Photo
(The Free & Private ChatGPT Method)
Finding the perfect sunglasses shouldn't be a guessing game. The secret? It all starts with knowing your face shape.
But here's what most face shape guides won't tell you: identifying your face shape is just the beginning. The real magic happens when you get a curated collection of styles that actually work for your shape.
While there are many "instant" face shape detector tools online today, most require you to upload your personal photos to their servers. If you value your privacy but still want an accurate, AI-powered analysis, there is a better way.
We've discovered that ChatGPT is incredibly accurate at identifying face shapes from a photo—and it keeps your data private. You just have to ask it the right way.
Here is the exact, step-by-step method to determine your face shape for free using ChatGPT, plus what to do once you have your results.
Step 1: Take the Perfect Photo
For AI to accurately analyze your facial proportions, it needs a clear, unobstructed view. Use natural lighting, ideally facing a window so your face is evenly lit. Keep your head straight and look directly at the camera without tilting up, down, or to the side. Pull your hair back completely so your full hairline and jawline are visible, and keep your expression neutral, since a large smile can slightly change your cheek shape. A close-up photo taken from about arm’s length away is ideal.
Step 2: Ask ChatGPT the Right Way
Open ChatGPT on your phone or go to chatgpt.com. Upload the photo you just took, then copy and paste the prompt below:
"Please act as an expert stylist and analyze this photo to determine my face shape. Consider the width of my forehead compared to my cheekbones and jawline, plus the overall length versus width of my face. Based on these proportions, is my face shape round, oval, square, or heart-shaped? Please explain your reasoning and describe the key features that led to your conclusion."
Step 3: Get Your Results
ChatGPT will analyze your proportions and tell you your face shape, explaining exactly why it chose that shape based on your forehead, cheekbones, and jawline.
After over 25 years in the eyewear business, we've learned that most women fall into one of four main face shapes.
Round Face Shape: Face width and length are similar, with a soft curved jawline and fuller cheeks.
Oval Face Shape: The forehead is slightly wider than the chin, with balanced proportions and gentle curves.
Square Face Shape: A strong, angular jawline with similar width across the forehead and jaw.
Heart Face Shape: A wider forehead with a narrower chin and more prominent cheekbones.
Step 4: Come Back Here for the Real Magic!
