Pixels decide print quality, dpi only describes it
A print is sharp when enough pixels cover each inch of paper. The printing guides we checked agree on 300 pixels per inch at the final printed size as the target for photos that people look at up close. The formula is plain: pixels equal print inches multiplied by pixels per inch. An 8x10 print at 300 ppi therefore needs 2,400 × 3,000 pixels.
The dpi number stored in a file, often 72 or 96, is only a label. Changing that label does not add detail. What counts is the pixel width and height of the image, compared with the size at which you place it. The table shows the pixels you need at 300 ppi, and the lower 150 ppi figure some printers accept for pieces viewed from further away.
| Print size | Ratio | Pixels at 300 ppi | Pixels at 150 ppi |
|---|
| 2 × 2 in (printed resume) | 1:1 | 600 × 600 | 300 × 300 |
| 4 × 6 in | 2:3 | 1,200 × 1,800 | 600 × 900 |
| 5 × 7 in | 5:7 | 1,500 × 2,100 | 750 × 1,050 |
| 8 × 10 in | 4:5 | 2,400 × 3,000 | 1,200 × 1,500 |
| 11 × 14 in | 11:14 | 3,300 × 4,200 | 1,650 × 2,100 |
The 8x10 is the size photographers and portrait guides name as the standard headshot print. The exact requirement is the 2,400 × 3,000 pixels above, which is 7.2 megapixels.
What the label hides: two delivery disputes from photography forums
In an r/acting thread, someone received "high-res" headshots of 600 × 900 pixels, labeled 300 dpi, and was asked to buy 8x10 prints from the photographer. Replies did the same sum as the table: an 8x10 at 300 dpi needs 2,400 × 3,000 pixels, so those files cover roughly 2 × 3 inches. In an r/AskPhotography thread, team portraits delivered at about 1,500 × 1,200 pixels came out near 150 ppi at 8x10, and most replies called files that small a delivery mistake. The lesson is that a ppi number on a delivery page is only as good as the width and height behind it.
The largest print your file can support
Turn the formula around: divide the pixel width by 300 and you get the widest print in inches that still looks crisp. Here is that calculation for files you probably have.
| Your file | Widest print at 300 ppi | What it means in practice |
|---|
| 400 × 400 px (LinkedIn upload minimum) | 1.3 in | Fine for a screen, too small for any print |
| 800 × 800 px | 2.7 in | Business card corner, small resume photo |
| 1,024 × 1,024 px | 3.4 in | Brochure bio, small flyer, staff page in a printed report |
| 3,000 × 4,000 px (12 MP phone photo) | 10 × 13.3 in | A full 8x10 with room to crop |
A face cropped out of a group shot often prints badly for the same reason: the crop throws away most of the pixels before the print starts.
Cropping to 4:5 costs pixels you may not have to spare
An 8x10 is a 4:5 rectangle. Phones usually shoot 3:4 and many tools export squares, so a crop is nearly always needed. Cropping a 3,000 × 4,000 portrait to 4:5 leaves 3,000 × 3,750 pixels, which still covers a 10 × 12.5 inch print. A 1,024 × 1,024 square cropped to 4:5 leaves about 819 × 1,024 pixels. Stretched across eight inches, that is roughly 102 pixels per inch, well under the 150 some printers tolerate. The same square cropped to a 5 × 7 gives about 731 × 1,024 pixels, or 146 pixels per inch, which is borderline but workable for a handout.
Screens are a different problem, and dpi plays no part
On a screen, only pixel dimensions matter. LinkedIn's help page for failed uploads states the limits: a profile photo between 400 × 400 and 7,680 × 4,320 pixels and a file of at most 8 MB. Those are upload limits, not a target, so a larger original gives the platform more to work with when it scales your picture down.
For a company website, the numbers come from the page layout. A photographer in an r/photography thread describes the cost of guessing too low. A staff site showed 600 × 712 pixel portraits sharply in the grid, but the profile pages enlarged them and they turned soft, and the same files were later printed in a brochure and looked bad. Replies advised never exporting web portraits that small, and one suggested a 1,080 pixel short edge as a simple default.
For web use, a JPG in the sRGB color space is the usual choice. Platforms recompress what you upload, so start from a clean original rather than a screenshot of your own profile.
Upscaling does not recover detail, and it can change a face
Enlarging a small image lowers its effective resolution, and the print softens. Upscaling programs sharpen by inventing plausible texture, and invented skin and eye detail can drift away from how you look. If a print needs more pixels than you have, print smaller, reshoot, or ask your photographer for the full-size file.
Where a generated headshot fits
Profilfoto KI creates a realistic portrait from your own selfies in the style you choose, in about three to five minutes and without a studio appointment. The service does not state a print resolution, so treat the pixel dimensions of the file you download as the only fact. Use the second table above to see which print size they support: websites, profiles, email signatures and slide decks never need more than screen sizes, while a full 8x10, a poster or a banner needs the 2,400 × 3,000 pixels or more. If a large print matters, check the real dimensions first and, if the job is important, book a photographer.
The first photo is free and carries a watermark, so you can judge the likeness and the framing before buying anything. Packages are one-time payments: two photos for €4.99, twelve for €29 and forty for €79, with no subscription. Your uploaded selfies are stored in Frankfurt and deleted automatically after 90 days at the latest.
Questions people ask
Is 150 ppi good enough for an 8x10 headshot?
It is soft but usable for a handout. Forum photographers treat 300 ppi (2,400 × 3,000 pixels) as the standard for a sharp 8x10 and call 150 ppi delivery files too small for a paid job. A 1,200 × 1,500 pixel file lands at exactly 150 ppi.
Do I need 72 dpi for the web or 300 dpi for print?
Neither number matters on a screen, which shows the pixel width and height and ignores the dpi tag. For print, divide the pixels by the printed inches and check the dimensions, not the label.
What pixel size should a headshot be for a company website?
Export a bit larger than the largest place the photo appears, profile pages included. In one thread, 600 × 712 pixel portraits looked fine in a grid and blurry on the profile page.
Why is my LinkedIn photo blurry after I upload it?
LinkedIn accepts 400 × 400 up to 7,680 × 4,320 pixels and 8 MB. One user in an r/linkedin thread resized to exactly 400 × 400, tried several dpi settings and still saw a soft result. Upload a larger original, not a screenshot or an already compressed copy.
Are 12 megapixels enough for an 8x10?
Yes. A 12 megapixel photo is about 3,000 × 4,000 pixels, and an 8x10 needs 7.2 megapixels at 300 ppi. A copy sent through a messaging app or a screenshot is often far smaller, so use the original file.
Which file format should I use?
JPG in sRGB is the safe default for web and most uploads. PNG is only needed for transparency. For professional printing, ask your printer, since some presses ask for CMYK files.
