How many times larger is 4K UHD resolution compared to standard HD?

Explanation:
The number of pixels in a resolution determines how much detail it can show. 4K UHD has a resolution of 3840 by 2160, while standard HD is 1920 by 1080. Each dimension is doubled (3840 is 2 × 1920, and 2160 is 2 × 1080). Doubling both width and height multiplies the total pixel count by 2 × 2, which is 4. So 4K UHD has four times as many pixels as standard HD. In numbers, about 8.29 million pixels versus 2.07 million, confirming the fourfold increase.
