Here is how the Image File Size equation looks like.

4.25 = 1000 \cdot \frac{34}{8000}

4.25bits = 1000px \cdot \frac{34bits}{8000}

4.25 = 1000 \cdot \frac{34}{8000}

Image File Size Solution

Follow our step by step solution on how to calculate Image File Size?

FIRST Step Consider the formula

S i = R i \cdot \frac{B d}{8000}

Next Step Substitute values of Variables

∴

S i = 1000px \cdot \frac{34bits}{8000}

Next Step Prepare to Evaluate

∴

S i = 1000 \cdot \frac{34}{8000}

LAST Step Evaluate

∴

S i = 4.25bits

Image File Size

Image File Size refers to the amount of storage space an image occupies on a device or network, typically measured in bytes, kilobytes (KB), megabytes (MB), or gigabytes (GB).

Symbol: S_i

Measurement: Data StorageUnit: bits

Note: Value should be greater than 0.

Formulas to find Image File Size

Image Resolution

Image Resolution refers to the amount of detail an image holds, determined by the number of pixels per unit area, influencing clarity, sharpness, and quality of visual representation.

Symbol: R_i

Measurement: ResolutionUnit: px

Note: Value should be greater than 0.

Formulas to find Image Resolution

Bit Depth

The Bit Depth is the second factor affecting image file size is bit depth. Bit depth is the storage space each pixel needs to represent the range of different colors.

Symbol: B_d

Measurement: Data StorageUnit: bits

Note: Value should be greater than 0.

How to Evaluate Image File Size?

Image File Size evaluator uses Image File Size = Image Resolution*Bit Depth/8000 to evaluate the Image File Size, The Image File Size formula is defined as the amount of space that the image file takes up on your memory card, or internal memory if your camera has one. It is measured in megabytes. The actual file size depends on the image size and image quality settings selected on the camera. Image File Size is denoted by S_i symbol.

How to evaluate Image File Size using this online evaluator? To use this online evaluator for Image File Size, enter Image Resolution (R_i) & Bit Depth (B_d) and hit the calculate button.

FAQs on Image File Size

What is the formula to find Image File Size?

The formula of Image File Size is expressed as Image File Size = Image Resolution*Bit Depth/8000. Here is an example- 4.25 = 1000*34/8000.

How to calculate Image File Size?

With Image Resolution (R_i) & Bit Depth (B_d) we can find Image File Size using the formula - Image File Size = Image Resolution*Bit Depth/8000.

Can the Image File Size be negative?

No, the Image File Size, measured in Data Storage cannot be negative.

Which unit is used to measure Image File Size?

Image File Size is usually measured using the Bit[bits] for Data Storage. Nibble[bits], Byte[bits], Character[bits] are the few other units in which Image File Size can be measured.
