Resizing an image block in Squarespace is a straightforward process but it can differ slightly depending on which version of Squarespace you are using (7.0, 7.1, or Fluid Engine). Below, you will find detailed steps and considerations for resizing an image block across different versions.

Squarespace 7.1 and Fluid Engine

Squarespace 7.1 introduces a more flexible way to manage content blocks, and Fluid Engine provides even more control over layout and design. Here’s how to resize an image block:

Resizing in Squarespace 7.1:

1. Log In to Your Squarespace Account: Navigate to your website's dashboard.
2. Enter the Website Editor: Click on the "Pages" tab in the left-hand menu, select the page you want to edit, and click "Edit."
3. Select or Add an Image Block: If you haven’t yet added your image, click on the section where you want the image to go, hover over an insert point (a teardrop icon), and select the "Image" block.
4. Resize the Image Block:
   • Direct Dragging: Hover over the image block. You'll see resizing handles on the corners and sides of the block. Simply click and drag these handles to adjust the size of the image.
   • Side Panel: After selecting the image block, you may also notice options in the side panel where you can input specific dimensions or choose predefined size settings.

Resizing in Fluid Engine:

1. Access Fluid Engine: This is available if you're using a newer template that supports Fluid Engine or have transitioned to it in Squarespace 7.1.
2. Edit the Section: Enter the section where your image block resides by following similar steps as above. Click "Edit" on the section you want to modify.
3. Resizing Using Gridlines: When you drag the edges of the image block, you will see gridlines showing the structure of your page. This grid can help you align the image properly and maintain consistency with other elements.
4. Manual Adjustment: You can also use the "Resize" handles to change the image's proportions directly within the grid-based layout.

Squarespace 7.0

If you're using Squarespace 7.0, the process is slightly different and a bit more restricted:

1. Log In and Enter Page Editor:
   • Navigate to "Pages" in the Squarespace dashboard.
   • Select the page you want to edit and click "Edit."
2. Locate the Image Block:
   • Click on the relevant image block. If it doesn’t exist yet, add it by clicking an insert point and selecting “Image.”
3. Resize the Image Block:
   • Image Block Editor: Double-click on your image to open the image block editor.
   • Design Options: Within the image editor, adjust the "Design" settings which provide different image sizing options like "Small," "Medium," "Large," or "Original."

Additional Considerations

1. Aspect Ratio: Be aware that resizing the image could affect its aspect ratio, leading to distortion if not handled carefully. Squarespace generally tries to maintain aspect ratios, but manual adjustments can override this.
2. Grid Layouts: On some templates, resizing a block may influence the layout of other surrounding blocks due to the grid system Squarespace uses.
3. Mobile View: Always check how your resized images look on different devices. Squarespace allows you to switch between desktop, tablet, and mobile previews, ensuring your site's responsiveness and visual consistency across all devices.
4. Image Quality: Resizing images can sometimes affect their clarity. Ensure your original image is of high quality to avoid pixelation when making it larger. Conversely, reducing the size of a very high-resolution image can make the site load faster.

By following these detailed steps, you should be able to effectively resize image blocks in your Squarespace website, ensuring a polished and professional look.
