If you need to print photos, magazines, newspapers, or billboards, can you enlarge a photo for printing from an iPhone or Android phone? When you get some photos, you can only find the resolution information, such as 2000 × 3000 pixels. But the DPI, or dots per inch is the concern of a printer. What are the differences between DPI and resolution? How to enlarge and print a picture for printer without losing quality? Just learn more details about the ultimate guide from the article.
When you want to enlarge your photos to print with the best quality, you should know what is the ideal size for printing photos. But before an image gets printed, its pixels don't really have dimensions or sizes. What really makes a difference is DPI. If an image is higher in DPI, it is better in image quality. Usually, the print qualities of photos are divided into 3 levels.
Decent: 100-150DPI
Above Average: 150-300DPI
Professional Grade: Above 300DPI
The larger the print size, the lower the dots per inch. If you want to increase the resolution of the printed picture, please choose the physical size of the printed picture reasonably. But when you zoom in the photo, you have to sacrifice resolution. Here you can enhance zoomed photo.

But it is not recommended that you enlarge the photo to more than twice the maximum size. Below 150DPI will be considered as low-resolution photos that cannot print without enlargement.
What you need to know is that the photos you take with your mobile phone, no matter how powerful the camera is, or some photos from streaming media, such as Facebook and Instagram, whose photos are usually 72DPI. But the good news is that it's easy to change when you want to know how to enlarge the image for printing.
