aspect ratio 계산기
The NexVaani Aspect Ratio Calculator simplifies the process of resizing and scaling visual assets while strictly preserving their intended proportions. Whether configuring YouTube thumbnails (16:9), Instagram Reels and TikTok videos (9:16), cinema ultra-wides (21:9), or classic photography prints (3:2, 4:3), this tool calculates exact pixel dimensions in real time.
The NexVaani Aspect Ratio Calculator determines proportional width or height dimensions for images and videos by entering any known width, height, or ratio (e.g., 16:9, 4:3) with 100% browser-based calculations.

The Mathematics of Aspect Ratios
An aspect ratio represents the proportional relationship between width (W) and height (H), expressed as W:H. To compute a new height (H2) given a new width (W2): H2 = W2 * (H1 / W1).
New_Height = New_Width / (Ratio_Width / Ratio_Height)기술적 제한 및 운영상의 제약
- Calculations assume rectangular pixel geometry (1.0 pixel aspect ratio).
주요 사양 및 기능
- Standard Ratio Presets – 16:9 (HD/4K), 4:3, 1:1 (Square), 21:9 (Ultrawide), 9:16 (Reels/Stories)
- Custom Ratio Input – Enter arbitrary width:height proportions
- Bidirectional Calculation – Enter new width to get height, or enter height to get width
- Client-Side Math – Calculations update locally in your browser without network requests
