Many mainstream smartphones measure about 7.6–8.3 millimetres thick.

The Claim

A typical smartphone is roughly 8 millimetres thick.

Verified by Lenz ·

The Short Version

The evidence supports this as a sound rule of thumb. Official specifications from major manufacturers place many mainstream smartphones around 7.6-8.3 mm thick, making “roughly 8 millimetres” a fair description of a typical handset. Thickness varies by segment, and quoted dimensions usually exclude camera bumps, but those details do not change the basic picture.

Caveats

  • Official thickness figures usually measure the body only and often exclude the camera bump, so real-world perceived thickness can be higher.
  • Phone thickness varies by category: budget models, gaming phones, foldables, and ultra-thin designs can sit well outside the ~8 mm norm.
  • The current market trend includes some thinner flagship models, so 8 mm is a rough central benchmark, not a fixed standard.
