Kikokotoo cha DPI na ukubwa wa kuchapisha
Kokotoa ukubwa wa kuchapisha na DPI
Inafanya kazi ndani ya kivinjari chako · Hakuna kupakia
Zana hii na maelekezo kwenye ukurasa huu bado ni kwa Kiingereza kwa sasa. Inafanya kazi vilevile: kila kitu kinafanya kazi ndani ya kivinjari chako.
300 DPI is the usual print-shop standard. To print larger at the same sharpness you need more pixels: changing the DPI number alone doesn't add detail. Related: Change Image DPI, Image Resizer.
Kivinjari chako ni cha zamani mno kuendesha zana hii. Tafadhali kisasishe, au tumia toleo la sasa la Chrome, Edge, Firefox au Safari.

How to use it
- Pick what you want to find: print size, pixels needed, or DPI.
- Enter the numbers, or read the size from an image.
- Read the result and the quality hint.
Rules of thumb
| DPI | Quality |
|---|---|
| 300 | Sharp prints you look at up close (photos, flyers) |
| 200–240 | Good for most prints |
| 150 | Posters seen from a step away |
| 72–100 | Screens only; prints look soft |
Good to know
- DPI only matters for printing. On screens, only the pixel size counts.
- A4 at 300 DPI needs 2480 × 3508 pixels.
- To change the DPI value stored in a file without changing the pixels, use the Change DPI tool.

Maswali yanayoulizwa mara kwa mara
How many pixels do I need for an A4 print?
2480 × 3508 at 300 DPI, or 1754 × 2480 at 212 DPI for a decent result.
Does changing DPI make my picture sharper?
No. Only more pixels do. The DPI value just tells printers how big to print.
