PPI
PPI=Pixels Per Inch.

sharp image of flowers
Sharp image, no pixelation. Yields the best print results for all print sizes.
slightly soft, pixelated image of flowers
Image is "soft," with slight blurriness. OK for most larger prints.
visibly pixelated image of flowers
Image is pixelated; you can see squares. May be OK for very large prints.

Pixelated / Pixelation
When an image or a print is pixelated (also described as having pixelation), you can see the individual colored squares of the image. Pixelation becomes visible at about 120 PPI (pixels per inch) or lower.

Legend

Very sharp

Pixels per inch of 250 or greater. Print will look very sharp, even close up.

Sharp

Pixels per inch of 150-249. Print will look sharp. Pixel per inch values closer to 150 might show very slight blurriness and pixelation within fine details when examined close up, but will not be noticeable when viewing from 2 feet away.

Soft

Pixels per inch of 120-149. Print will have some minor blurriness and pixelation when viewed close up, especially closer to PPI values of 120. Should be acceptable for larger prints when viewed from at least 3 feet away.

Pixelated

Pixels per inch of 50-119. Print will be noticeably blurry and pixelated when viewed at arm's length, with jagged edges within fine details. Use caution when ordering, especially for PPI values closer to 50. May be acceptable for very large prints, for example, 40"x60".

Unacceptable

Pixels per inch of less than 50. Print will be pixelated, with details looking jagged. Unacceptable print quality.
