Does image size affect print quality?
The Relationship Between Image Size and Print Resolution

The quality of printed photos is affected by the size and resolution of the image. The size of an image depends on its pixel dimensions. Resolution is the number of pixels per inch or dots per inch in print.Print Size Chart

Pixel Dimensions Full-Resolution Print Largest Print Possible
400×600 1.3” x 2” 4" x 6"
1000×1500 3.5" x 5" 10" x 15"
1200×1800 4" x 6" 12" x 18"
2000×3000 6.7" x 10" 20" x 30"

Here are some guidelines for getting the best quality prints from your photos:

  1. Start with the right size and shape.
  2. Understand DPI and PPI.
  3. Get a 300 DPI file.
  4. Apply some Sharpening.
  5. Download as a PNG + print.
  6. Check the DPI before you print.

Is 600 dpi good for printing : Generally, 300 DPI is great for small prints, while 600 DPI is amazing for large prints. If you're scanning documents or photos to be used on the web or in emails, 300 dpi is more than enough. If you want to print large photos or blow them up to poster size, 600 dpi will give you better results.

What image size is best for printing

Aspect Ratio – 6×4

Almost all cameras take photos with a 6×4 ratio. This means if you want ALL of your image to be printed, you need to your print to be printed at this ratio, which includes print sizes like 3×2”, 6×4”, 12×8” and 24×16”.

What causes poor print quality : Cheap paper can often be a key factor in producing poor-quality prints. The rough texture produces a high dust content which over time can affect print performance. Choosing a good quality paper will help reduce those print imperfections.

We can calculate that. Let's say our camera produces a photo with an image resolution of 1920×1080 px (1080p), and we want to print at 300 dpi, we use the formula px ÷ dpi to get the maximum print size at the given print resolution (dpi). We can make a print that is 6.4 x 3.6 inches (16.26 x 9.14 cm) @ 300 dpi.

PRINT SIZE 100 DPI 300 DPI
8 x 12 800 x 1200 2400 x 3600
11 x 14 1100 x 1400 3300 x 4200
12 x 18 1200 x 1800 3600 x 5400
16 x 20 1600 x 2000 4800 x 6000

Is 300dpi better than 600dpi

This means that the more dots per inch (dpi), the higher the print resolution. For example, a 300 dpi printer can print 300 dots per inch of page space, whereas a 600 dpi printer can print double that amount, creating a much higher quality print.How To Get Better Print Quality

  1. Make Sure You're Using the Best Software. The software you use can make a difference!
  2. Check Your Monitor.
  3. Understand Your Printing Languages.
  4. Check Your Operating System.
  5. Poke Around in Your Print Settings.
  6. Rethink Your Paper Stock.
  7. Consult a Print Expert.

The necessary DPI for print work depends on what you're doing. 300 dpi is sufficient for a simple flyer or business letter. A professional photographer, however, may not want to consider anything below 1200 dpi. If people are not going to view your prints close-up, you can get away with a lower DPI.

The higher the dpi the better the resolution and the better copy/print quality. For example, 1200 X 1200 dpi will give you better resolution or copy/print quality than 600 X 600 dpi, thus giving you better copy/print quality and better half tones.

Does file size matter when printing : What matters is the amount and type of compression used. The JPEG format especially uses lossy compression that can be modified to squeeze a given number of pixels into smaller and smaller file sizes–to a point–with increasing losses of image quality.

How many pixels for high quality print : The best resolution for printing is 300 PPI with placed images at 100% or smaller. Increasing the size of an image will lower its final PPI. At 300 PPI, an image will appear sharp and crisp. This is considered to be high resolution or high-res.

How to fix poor print quality

Overall Print Quality is Poor

  1. Run a nozzle check to see if any of the print head nozzles are clogged.
  2. Perform a print quality adjustment.
  3. Make sure your paper meets the specifications for your product.
  4. Make sure the paper is not wrinkled, folded, or bent.
  5. Make sure your ink cartridges have not expired.


Achieving good print quality can depend on several factors, including the printer's maximum resolution, the quality of the original files being printed, and the number of dots the printer can produce. Other components, such as the quality of the toner or ink, can also impact print quality.The higher resolutions for small images are mostly useful for when you expect them to be blown up to much larger sizes for some uses. An A5 at 600 dpi can be blown up to A1 size and still be 150 dpi. 300 dpi is fine.

Is 1200 DPI good for printing : The necessary DPI for print work depends on what you're doing. 300 dpi is sufficient for a simple flyer or business letter. A professional photographer, however, may not want to consider anything below 1200 dpi. If people are not going to view your prints close-up, you can get away with a lower DPI.
