The general rule for high quality sharp prints is 300 pixels per inch. So an 8x10 inch print needs 8x300x10x300 = 7.2 megapixels. One can still make very nice 8x10 inch prints with less megapixels, but the lower the megapixel count, the softer the image.

For example, a 5 megapixel camera may have 2592 x 1944 pixels and a sensor size of 7.18 x 5.32 mm. Divide one dimension by the number of pixels in that dimension, e.g. 7.18 / 2592 = 0.0028 mm/pixel = 2.8 microns/pixel (a micron is one millionth of a meter or a micrometer).

(716) 229-0080. 2 Megapixel Security Cameras provide a resolution of 1080p that is equivalent to Blu-ray quality. If you are looking for economical HD security cameras, then 2MP surveillance cameras are a good starting point. There are 2 main types of 2MP cameras, i.e. 1080P IP Cameras and 1080P HDCVI Cameras.

A full-frame camera uses a sensor that's the same size as a single frame of traditional 35mm film, measuring 36 x 24mm. The more popular APS-C sensor size found in most DSLRs and mirrorless cameras measures 22 x 15mm. This means a full-frame sensor has more than 2.5 times the surface area of an APS-C sensor.

A 1-megapixel camera takes photos with a million pixels in them; a 20-megapixel camera captures 20 million pixel photos. Think of it like a grid that tells you how wide and tall the photo is. Consider the Nikon D7000, a 16-megapixel camera. It takes photos that are 4928 by 3264 pixels.

Yes. 18 megapixels is more than adequate to blow up your photos to a large size. I still use a Nikon D90 as a second camera and it only has 12 megapixels. I blow up decent clear prints of A3 size using this camera.

“If you have higher megapixels, that's more advantageous for printing, or for large displays. ... 12MP might sound like a small number, but a good 12MP image is enough to print an A4 image at 300ppi. It's doubtful that many smartphone users would print photographs even at that size, so 12MP is 'good enough' for most.
