Customize the size and layout of your product media by changing the product **Media** settings. You can also make the product details **Sticky**, so they remain fixed in-place when scrolling down.
STEPS
In your theme editor (**Customize**):
1. Click on the **Product overview** section to open the settings.
2. (*Optional*.) For long product forms, uncheck the **Enable sticky sidebar** checkbox so customers can easily access product details and buy buttons when they scroll down.
> The default "sticky" sidebar keeps the product form in view when scrolling.
3. Select a **Gallery style** to change the layout of your product media.
> **Grid** displays product images in two columns. See [Minimal demo](https://spark-theme-chic.myshopify.com/products/aude-trousers-light_fawn) example.
> **List** displays product images in on column. See [Clean demo](https://spark-theme-clean.myshopify.com/products/moisture-riser-cream) example.
> **Thumbnails** displays all product images as small clickable images next to the main product image. See [Chic demo](https://spark-theme-chic.myshopify.com/products/aude-trousers-light_fawn) example.
4. Select the **Gallery size** of your product media. Either **Small**, **Medium**, or **Large**.
> The width of the product details will increase or decrease according the gallery size.
> Set the **Mobile gallery style**. Either **Thumbnails** or **Carousel**.
5. To make all product media a uniform shape, set the **Image aspect ratio** to crop your images to **Square**, **Landscape**, or **Portrait**.
> The default **Natural** setting displays the original orientation of your product media.
6. Uncheck the **Enable video looping** checkbox to make product videos play a single time after customers click play.
> See Shopify's [Product media](https://help.shopify.com/en/manual/products/product-media) guide to learn more.
7. Uncheck the **Product lightbox** option if you don't want your product images to appear in a full-size "lightbox" when clicked.
8. Click **Save**.
