You've created a beautiful 3D text image but don't know what resolution to export. Too small and it's blurry after upload; too large and the file times out. Every platform has different requirements and you can't remember them all.
This article compiles recommended resolution values for mainstream platforms and use cases, organized by scenario for quick lookup — one reference to solve all your sizing questions.
01 Social Media Platform Size Reference
Different social platforms have vastly different image display specs. Here are the latest 2025 recommended sizes:
YouTube Thumbnail: 1280×720 px (16:9), max 2 MB. This is the most critical size — 90% of viewers decide to click based on the thumbnail. 3D text from Cube 3D Text maintains good clarity at this dimension.
Bilibili Cover: Recommended 1146×717 px. Bilibili crops covers in both 16:9 and 1:1, so core content should stay within the centered safe area.
Instagram Post: 1080×1080 (square), 1080×1350 (portrait 4:5), 1080×566 (landscape 1.91:1). IG auto-compresses quality, so originals should be at least 1.5× display size.
WeChat Article Header: Recommended 900×383 px (2.35:1). Extreme landscape ratio — text can't be too tall. Cover image: recommended 500×500 px.
02 Video & Streaming Dimensions
If your 3D text will be used in video editing or streaming, match it to the video frame resolution:
1080p Full HD video: 1920×1080 px. The most common video resolution today. Cube 3D Text exports at fullscreen browser window generally meet this requirement.
4K Ultra HD video: 3840×2160 px. Requires operating on a 4K or Retina display for sufficient pixel density. Alternatively, export a smaller PNG and scale up in your video editor — pixel-block textures actually hold up better than photos when enlarged.
Stream overlays: Typically match the stream output resolution (1920×1080 or 1280×720). Overlays are transparent PNGs layered on the stream, so you only need to export the text area, not the full frame.
Block text's pixelated style has a unique advantage: even when scaled up 200%, the deliberately "pixel-art" look actually improves rather than degrades — unlike photos that blur when enlarged.
03 Presentation & Document Dimensions
PowerPoint standard slide size is 1920×1080 px (widescreen 16:9) or 1024×768 px (standard 4:3). 3D text images in PPT don't need to cover the entire slide — typically 1/3 to 1/2 of the area suffices.
For a 16:9 slide, if 3D text occupies half the width, 960×540 px is sufficient. For a title spanning the full page, aim for approximately 1920×300 px.
When inserting into PPT, disable PowerPoint's "auto-compress images" feature (File > Options > Advanced > Do not compress images) to preserve the crisp block textures of your 3D text.
04 Print Resolution Requirements
If you need to print your 3D text (posters, greeting cards, T-shirts), resolution requirements are far higher than screen display. The print baseline is 300 DPI (300 pixels per inch).
Example: Printing a full-bleed image on A4 paper (~8.27×11.69 inches) requires at least 2481×3507 px. This exceeds typical browser screenshot dimensions. For print, operate on the largest possible screen to maximize resolution.
However, block text has a print advantage: since the pattern consists of regular pixel blocks, vectorizing the PNG (via Illustrator Image Trace) produces an infinitely scalable vector — completely solving print resolution issues.
Greeting card prints (typically 5×7 inches) only need 1500×2100 px for 300 DPI — entirely achievable with a fullscreen browser screenshot.
FAQ
What's the relationship between DPI and pixel dimensions?
DPI (dots per inch) determines pixel density at physical size. 1000 pixels at 300 DPI prints about 3.3 inches wide; at 72 DPI, it's 13.9 inches wide. Screens typically use 72–96 DPI; print requires 300 DPI.
Will enlarging an image make it blurry?
Regular photos blur when enlarged, but block text is special — since it's already pixelated by design, enlarging actually enhances the "pixel game" aesthetic. Beyond 300% upscale, jagged edges may become noticeable.
Why does WeChat always compress my images?
WeChat compresses large images to approximately 1080 px wide by default. Choose "Send as original" when sending to bypass compression. Moments posts can't avoid compression — keep uploaded images under 1080 px wide to minimize re-compression effects.
How do I reduce PNG file size if it's too large?
Method 1: Use an image compressor for lossless PNG compression — typically reduces size by 30–60%. Method 2: If transparency isn't needed, export or convert to JPG format for dramatically smaller files.
What resolution are Retina display screenshots?
Retina displays have 2× the physical pixels of logical pixels. For example, a canvas displaying at 960×540 produces a 1920×1080 px Retina screenshot. This is the simplest way to get high-resolution exports.
