A lightweight yet powerful resolution assistant for ComfyUI.
It allows you to select image size using human-friendly dropdowns instead of typing width and height manually.
Designed for:
✓ EmptyLatentImage
✓ Video / TikTok / IG / Story formats
✓ ControlNet / AnimateDiff / Sampler
✓ Latent-safe (auto snap to 64)
🧠 Smart width & height calculation
– Choose Resolution Preset (HD, FullHD, 2K, 4K, 8K)
– Choose Aspect Ratio (1:1, 9:16, 4:5, 21:9 etc.)
– Output: clean width and height (INT values)
⚙ Latent-safe scaling
– Automatically snaps resolution to the nearest multiple of 64
– 100% compatible with latent operations
