About the smartphone

Modern smartphones are thin glass-and-metal slabs about the size of a hand. As a typical example, Apple's iPhone 17 is 149.6 mm tall, 71.5 mm wide and 7.95 mm thick, and weighs 177 g. Sizes vary by brand and model, and larger phones are taller and heavier.

  • Apple lists the iPhone 17 at 5.89 in tall, 2.81 in wide and 0.31 in deep, weighing 6.24 oz. [1]
  • Apple's comparison page shows iPhone 18 Pro and 18 Pro Max models but no base iPhone 18, so the iPhone 17 is the newest standard iPhone. [2]

How many fit?

  • ≈ 11 × Smartphone · height lined up end to end match the Human · height
  • ≈ 470 × Smartphone · weight on the scales weigh as much as Human · body mass
  • ≈ 3 × AA battery · overall height lined up end to end match the Smartphone · height
  • ≈ 7.7 × AA battery · weight on the scales weigh as much as Smartphone · weight

Counts divide one sourced figure by another. "End to end" uses each object's main measurement; weight and volume rows appear only when both figures are sourced.

How it compares

  • 3× A smartphone is about 3 times as tall as an AA battery. See side by side
  • 1.7× A smartphone is about 1.7 times as tall as a credit card is wide. See side by side
  • 1/1 A smartphone is about as tall as a US dollar bill is long. See side by side
  • 1/4.6 A soccer ball is about 4.6 times as around as a smartphone is tall. See side by side
  • 1/2 A sheet of A4 paper is about 2 times as tall as a smartphone. See side by side
  • 1/11 An average adult is about 11 times as tall as a smartphone. See side by side

Factors compare the height of a smartphone with each object’s own main measurement (height for a human). Where a size varies, the factor is given as a range.

Notes on these figures

  • Smartphone sizes vary widely by brand and model; the iPhone 17 is used as one representative example.
  • Apple does not publish a volume figure, so volume is left out.
