# Aspect Ratios & Crop Guides

Aspect ratios control the shape of your rendered output. Glossi supports three standard ratios and, for enterprise users, crop guide overlays to help maintain consistent framing across your product catalog.

### Aspect Ratios

Glossi supports three aspect ratios:

* **16:9 (Landscape)** — The default. Ideal for website heroes, video content, and presentation slides.
* **1:1 (Square)** — Perfect for social media posts, website thumbnails, and marketplace listings.
* **9:16 (Portrait)** — Optimized for mobile displays, social stories, and vertical content.

#### Changing the Aspect Ratio

Open the **camera settings popover** by clicking the gear icon in the top-right of the studio toolbar. Select your desired ratio from the **Aspect Ratio** dropdown.

When you switch aspect ratios, the viewport adjusts to show the new framing. Your product remains centered in the frame. The selected aspect ratio applies to all renders exported from the current session.

### Crop Guides (Enterprise)

Crop guides are semi-transparent overlays displayed on top of the viewport to help you position your product consistently. They're useful for maintaining precise framing standards across large teams and product catalogs.

Crop guides are available to enterprise users and only apply to the **1:1 aspect ratio**. The dropdown is disabled when other ratios are selected.

#### Using Crop Guides

In the same camera settings popover:

1. Select **1:1** as your aspect ratio.
2. Choose a crop guide from the **Crop Overlay** dropdown:
   * **None** — No overlay (default).
   * **General** — A general-purpose framing guide.
   * **Large** — A framing guide for larger product compositions.
   * **Custom** — Upload your own guide image (see below).
3. Adjust the **opacity** (0–100%) by clicking the opacity value next to the guide name. The default is 50%.

#### Custom Crop Guides

Enterprise users can upload custom crop guide images to match specific brand standards:

1. Select **Custom** from the crop guide dropdown.
2. Choose an image file to upload (transparent PNGs work best).
3. The uploaded guide appears as an overlay on the viewport at 50% opacity.

Custom guides are particularly useful for maintaining exact positioning requirements across product categories and ensuring consistency when multiple team members are creating content.

> **Note:** Crop guides are visual aids only — they appear in the viewport to help with composition but are not included in the final rendered output.
