About Image Megapixel Calculator
The Image Megapixel (MP) & Sensor Resolution Calculator computes total megapixels ($W \times H / 1,000,000$), standard camera sensor aspect ratios (4:3, 3:2, 16:9), maximum lossless print sizes at 300 DPI, and uncompressed RAW bit depths.
How to Use Image Megapixel Calculator
Step 1
Upload an image file or enter Width and Height in pixels.
Step 2
Review computed Megapixel rating and aspect ratio.
Step 3
Inspect physical print size charts at 300 DPI and 150 DPI.
Step 4

Practical Use Cases for Image Megapixel Calculator
Calculating Camera Sensor Megapixels from Pixel Dimensions
Find out the exact megapixel rating for non-standard image dimensions (e.g. 6000x4000 = 24.0 MP, 8256x5504 = 45.4 MP).
Verifying Maximum Physical Print Dimensions at 300 DPI
Calculate the maximum physical gallery print size (inches/cm) an image can achieve at professional 300 DPI without pixelation.
Input & Output Examples
Evaluating 24MP Camera Image
Width: `6000px`, Height: `4000px`
Megapixels: `24.0 MP` | Ratio: `3:2` | Max 300 DPI Print: `20.0" x 13.3"` (50.8cm x 33.9cm)
