Why does the app use 375? Revealing the golden dimensions of mobile design

In mobile app and web design, a width of 375px is a common baseline size. Many designers and developers choose this value as the standard width of design drafts, especially for mobile devices such as iPhone. So why has 375px become the industry default? This article will analyze this phenomenon from three aspects: technology, equipment and user habits, and attach the hot topic data of the entire network in the past 10 days for reference.

1. The origin of 375px: the balance between equipment and technology

The width of 375px is closely related to the screen resolution of the iPhone. Taking iPhone 6/7/8 as an example, its logical resolution is 375×667 (pt), while its physical resolution is 750×1334 (px). Designers usually use logical resolution (375pt) as a benchmark, and then scale it by 2x or 3x to adapt to different devices. This design specification gradually became an industry standard and was adopted by other Android devices.

2. Advantages of 375px: Efficient collaboration between design and development

1.Simple development and adaptation: A 375px design draft can be directly scaled by 2 times or 3 times, reducing the computational complexity during development. 2.High design consistency: The same size is suitable for most mainstream devices, reducing the cost of multi-version adaptation. 3.Matching user habits: Mobile users have adapted to this width of visual experience, reducing learning costs.

3. Hot topics and content on the entire network in the past 10 days

The following are the hot topics on the Internet recently (as of October 2023), covering technology, society, entertainment and other fields:

4. Summary: The future trend of 375px

Although the resolutions of folding screens and Android devices are more diverse, 375px will still be the core reference value for mobile design in the short term due to its historical accumulation and development convenience. In the future, with the popularization of dynamic layout technologies (such as Flexbox and Grid), the size standards of design drafts may be further simplified, but the "golden status" of 375px will still be difficult to shake.

Through the analysis of this article, I believe you will have a clearer understanding of the reasons for choosing 375px in App design. Whether developers or designers understand the logic behind this standard, they can complete cross-device adaptation work more efficiently.
