How many megapixels is 4K?

To calculate how many megapixels 4K resolution represents, we need to multiply the horizontal and vertical pixel counts of a 4K display, then divide by 1 million (since 1 megapixel = 1 million pixels).

4K Resolution:

• Standard 4K is 3840 x 2160 pixels.

Calculation:

• Multiply the horizontal and vertical pixel counts: $$3840 \times 2160 = 8,294,400 \text{ pixels}$$
• Divide by 1 million to convert to megapixels: $$\frac{8,294,400}{1,000,000} = 8.29 \text{ megapixels}$$

Conclusion:

• 4K resolution (3840 x 2160 pixels) is approximately 8.3 megapixels.

For reference:

• Full HD (1080p) is 1920 x 1080 pixels, which is about 2.1 megapixels.
• 8K resolution (7680 x 4320 pixels) is approximately 33.2 megapixels.

So, a 4K display is roughly 8.3 megapixels in terms of image resolution.
