What is DPI and why does it matter?
DPI stands for Dots per Inch — the number of print dots per inch (2.54 cm). The value describes how densely the print dots are placed on the paper. The higher the DPI value, the finer and sharper the print looks — and the smaller the print you can produce from a given resolution while staying sharp.
Put simply: DPI is the conversion factor between digital resolution and physical print size. A file with 3000 × 2000 pixels yields a print of 25.4 × 16.9 cm at 300 dpi — at 150 dpi the same print would be twice as large, but with visible pixels up close.
For photography, these rules of thumb apply:
Classic screens work at 72–96 dpi. For digital sharing or social media that's perfectly fine, but far too low for printing — the result would look muddy and pixelated. Important: Retina and HiDPI displays (MacBook, iPhone, iPad, modern monitors) have far more — usually 220 to over 450 ppi. The 72-dpi figure refers only to the historical web convention, not to the actual pixel density of modern screens.
Posters, banners and shop-window prints are typically printed at 150 dpi. From a viewing distance of 1–2 m, the result is sharp and professional.
For wall art and posters, 200 dpi is a good compromise: a sharp print that still holds up at half an arm's length — and allows larger sizes than 300 dpi.
The industry standard for photo prints, books and magazines. At 300 dpi, the print is pixel-free and sharp even from very close up. This is the value labs expect for photo prints.
600 dpi is used for extremely fine prints — for example, detail shots printed under 20 × 30 cm where every hair or texture needs to be razor-sharp. Most eyes can't tell the difference above 300 dpi.
The right resolution for different print sizes
The formula is simple: print width in cm = (pixel width ÷ DPI) × 2.54. Conversely: to find out how many pixels you need for a given format, calculate format in cm ÷ 2.54 × DPI.
For a sharp A3 print (29.7 × 42 cm) at 300 dpi you need at least 3508 × 4961 pixels — that's about 17 megapixels. A modern APS-C camera with 24 megapixels comfortably exceeds that.
| Print Format | Size (cm) | Pixels at 300 dpi | Min. MP |
|---|---|---|---|
| 10 × 15 | 10 × 15 cm | 1181 × 1772 px | ~2 MP |
| 13 × 18 | 13 × 18 cm | 1535 × 2126 px | ~3.3 MP |
| A4 | 21 × 29.7 cm | 2480 × 3508 px | ~8.7 MP |
| A3 | 29.7 × 42 cm | 3508 × 4961 px | ~17.4 MP |
| A2 | 42 × 59.4 cm | 4961 × 7016 px | ~34.8 MP |
| A1 | 59.4 × 84.1 cm | 7016 × 9933 px | ~69.7 MP |
| A0 | 84.1 × 118.9 cm | 9933 × 14043 px | ~139.5 MP |
As you can see: A1 at 300 dpi is challenging even for 40-megapixel cameras. But in practice that's not a problem — large formats are rarely viewed from 30 cm away. For wall art from A2 upward, 150–200 dpi is completely sufficient and halves the pixel requirement.
Fujifilm recommendations for printing
Fujifilm cameras are known for their outstanding image quality — and the current models are also excellent for large-format printing:
- Fujifilm X-T5 and X100VI (40 MP · 7728 × 5152): The 40-megapixel sensor allows prints up to about 65.5 × 43.6 cm at 300 dpi — that's larger than A2 and close to A1. At 200 dpi it easily covers A1 (59.4 × 84.1 cm), and at 150 dpi even A0.
- Fujifilm X-H2S and X-S20 (26 MP · 6240 × 4160): At 300 dpi, a maximum of 52.8 × 35.2 cm — that's between A3 and A2. For high-quality posters up to A2 at 200 dpi, the resolution is ideal.
- In general: Fujifilm's image processing (Film Simulations, X-Trans sensor) produces particularly smooth highlights and soft transitions that look beautiful when printed. Printed at 200 dpi, Fujifilm images often look better than expected.
If you regularly plan to print large formats, it's worth paying attention to maximum RAW resolution while shooting rather than upscaling afterward. Careful white balance and controlled ISO also pay off when printing — noise is much more visible in print than on screen.
You can learn more about the technical relationship between sensor, resolution and image quality in the Depth of Field Calculator, which shows how megapixels and sensor size also affect depth of field.
Printing in practice: what really matters
Theory and practice sometimes diverge when it comes to printing. What really determines the quality of a print isn't just megapixels and DPI:
Motion blur, missed focus or camera shake are ruthlessly visible in print. A technically perfect shot looks better at 150 dpi than a blurry one at 300 dpi.
Grainy high-ISO shots often still look acceptable on screen — but in a large-format print, the noise becomes much more visible. Keep ISO as low as possible when planning large-format prints.
Monitors display colors differently than printers do. Before a large-format print, it's worth doing a soft proof with the print lab's ICC profile — otherwise colors and contrast can shift significantly.
Every crop costs pixels. If you crop away 20% of the image, you also lose 20% of the usable resolution. Plan your framing while shooting if you have large-format prints in mind.
How the calculation works
The print size calculator uses the following formula:
- Width (cm) = (pixel width ÷ DPI) × 2.54
- Height (cm) = (pixel height ÷ DPI) × 2.54
The factor 2.54 converts inches to centimeters (1 inch = 2.54 cm). The DIN format overview shows, for each standard format, whether your resolution is sufficient at 300 dpi (photo print) and 150 dpi (large format).
The rating is based on the maximum print size relative to the format's area: if your pixel resolution is sufficient for a given DIN format at 300 dpi, the row gets a green checkmark. At 150–299 dpi a warning appears, and below that, a red cross.
By the way: similar considerations also apply to depth of field — more megapixels allow not only larger prints, but also more room to crop without losing sharpness.
Frequently asked questions about the print size calculator
How big can I print my photo?
It depends on your camera's pixel count and the DPI value you want. Use the calculator above: choose your camera model, set it to 300 dpi (photo print), and you'll instantly see the maximum print size in cm as well as the DIN format comparison. A 40 MP camera (7728 × 5152 pixels) prints up to about 65 × 44 cm at 300 dpi — close to A1.
What DPI do I need for photo printing?
For professional photo prints, 300 dpi is the standard. Print labs (CEWE, WhiteWall, dm-Fotowelt) generally require 300 dpi for their minimum sharpness guarantee. For posters from A2 upward and wall art viewed from a distance, 150–200 dpi is perfectly sufficient. 72 dpi is suitable only for screen display.
What do megapixels really mean for printing?
Megapixels describe the total number of pixels (width × height). More megapixels allow either larger prints at the same DPI, or the same print after heavy cropping. 24 MP is enough for A2 at 300 dpi, 40 MP almost enough for A1. But beware: sharpness, ISO noise and color profile are at least as important for print quality as raw pixel count.
Can I enlarge my photo afterward (upscaling)?
Yes, with modern AI upscaling software (Topaz Gigapixel, Adobe Super Resolution, ON1 Resize) photos can be enlarged by a factor of 2–4 with no visible loss of quality. This is especially useful if you want to use an older image for a large format. The best results come from technically flawless shots — upscaling doesn't fix noise or blur.
Can I print A1 with the Fujifilm X-T5?
Yes, with some limitations. The X-T5 has 40 MP (7728 × 5152 pixels). At 300 dpi that yields a maximum of 65.5 × 44 cm — A1 is 59.4 × 84.1 cm, so the short side is nearly reachable, while the long side exceeds the pixel limit. In landscape orientation, A1 fits comfortably at 200 dpi: 59.4 cm corresponds exactly to 46.8 cm at 150 dpi × 1.26 — the calculator shows you the exact comparison.
