Technical Guide to X (Twitter) Sizes 2026: Sharpness and Retention
Introduction
On X in 2026, speed demands absolute visual clarity. The algorithm prioritizes threads with visual assets and native videos. Using pixelated graphics is a recipe for being ignored. Technical precision is a scroll retention tool.
The Challenge: The Crop and Technical Limitations
The mistake is ignoring how images are previewed. Text on the edges is usually cropped, forcing the user to make an extra click. In 2026, any additional effort reduces interaction.

Media Limits & X Premium+
- Maximum Weight: For images, stay under 5MB. For videos, X Premium+ users can upload up to 4GB, but for organic retention, the “sweet spot” remains lightweight files with instant loading.
- X Articles: For long-form content, the ideal header is 1280 x 720 px. :::

2. Content Formats

The Human Factor: The Psychology of Stopping
The brain stops before low cognitive load stimuli. A clean and perfectly proportioned image acts as a visual anchor. Sharpness is subconsciously perceived as a sign of truthfulness.
