How to find a celebrity to pornstar match guide.
Finding the right pornstar or a video to use in deepfake can be challenging. I would argue that it's actually the hardest part right after making a good faceset of your celebrity.
To help find one, there are a couple of tools and techniques that can be used. There are also a few things the potential match must have in order to work.
1. Grab a couple images of your celebrity from Google Images: 3-5 neutral expression faces with mouth closed, looking straight at the camera, frontally lit with no obstructions, and not a closeup to retain the shape of the face.
2. Feed them into the following websites:
Recommended:
https://pornstarbyface.com/ (usually best matches, most porn stars still active and easy to find)
3. Examine the suggested matches or, if you didn't get any decent/similar looking results, start looking manually by browsing model pages on sites of various porn studios/web series. Pay attention to the following aspects:
HEAD SHAPE AND MAJOR FACIAL FEATURES (MANDATORY):
There are a few shapes heads typically have. This is the most important aspect of a good match. If they are mismatched, the results may not look believable and, in some cases, head shape mismatch may cause your results to look unrecognizable. Check the following images that show all the various shapes to familiarize yourself with the major differences.

Make sure to match head shapes as well as possible:
- How wide and long the head is, as well as the general shape: does it appear more round or oval? Square or rectangular? Heart or diamond-shaped?
- How wide the jaw is: is it wider than the forehead or narrower? How high is it? Is the mouth below or above the line the jawline makes?
- Chin size and shape: is it wide and flat, making the face look more round or square? Or is it longer, narrower, and pointy, making the face look longer (even if the head itself isn't necessarily long)? A head can be long and narrow, but the chin may still be relatively short and wide. You can also have a shorter and wider head with a pointy chin.
- Height of the eyes and mouth in relation to each other, nose, and the bottom and top of the face should be similar.
- How large the forehead is: two heads may have the same shape, but some people will have a larger forehead with the whole face much lower, which the model will adapt to (less with WF, more with FF). Ideally, both faces should have facial features at about the same height with a similar size of the forehead.
- Are the cheeks bloated/puffy, flat, or sunken/hollow? This is heavily related to overall head shape and width of the jawline and forehead, but some people have quite bloated or very sunken cheeks. This may not matter for some celebs and certainly not if it's a slight mismatch, but avoid extremes.
You should also compare heads from the side:
- Check how far back the jaw goes and its shape: is it a strong, sharp, well-defined jaw, or is it barely noticeable with a much softer, less sharp angle where it connects to the skull under the ear?
- Is the nose of the pornstar larger or smaller than that of the celebrity? Ideally, the nose should be about the same size and at the same height. If it's much lower or higher, your result will adapt to it, which may reduce likeness. Additionally, pay attention to size: if the nose is larger, once you merge, the original nose will be visible under the swapped face (unless you do a lot of post-processing/inpaint the background/expand the mask a lot to cover it, but that has many disadvantages). If it's smaller, then when using the dst mask, the larger nose of the celebrity will be clipped by the mask, but that's still better than having a larger nose. Ideally, it should be of similar size and shape.
- Is the chin recessed or protruding (moved backward or forward when viewed from the side)?
FACIAL EXPRESSIONS (OPTIONAL, RECOMMENDED)
This may seem irrelevant, and for some celebs, it will be. But in other cases, when the celebrity we're trying to swap has very characteristic expressions, it may be necessary to also check how both faces smile, how wide they open their mouths. Matching a celebrity to a pornstar that expresses similarly can greatly improve the quality, but it is not as important as matching the general shape (even though you can get good results by matching similarly expressing celeb and pornstar even when their shapes aren't exactly the same).
SECONDARY FACIAL FEATURES (OPTIONAL)
These may matter less or be irrelevant for some, but for a perfect match, both faces should have these features matched. Pay attention to:
- If the face itself has a lot of large wrinkles on the forehead
- If there are pronounced nasolabial folds (wrinkles) around the mouth
- Shapes, size, and width of the eyes, mouth, nose, eyebrows, teeth
- Distance between eyes
The following don't really matter but sometimes may cause issues, particularly when masking or trying to color match the results:
- Skin tone/complexion/freckles/skin imperfections
- Scars, beauty marks, moles, piercings
HAIR, VOICE, HEIGHT, AND BODY DIMENSIONS (OPTIONAL, NOT MANDATORY OBVIOUSLY)
Obviously, these don't matter for the process at all, but it helps with the immersion if both are matched. Further explanation not required.
