Enable/Disable thumbs

The theme uses multiple thumb sizes which can be enabled from Theme Panel -> Block Settings. You can disable the unused ones to save some space on hard drive.

The thumbs size is also described here.

Uploaded Image Size

On our demo we use 1021 x 640 px large images.

WordPress doesn’t have an upscale function, if you upload small images on modules which use thumbs that are larger than the uploaded image the original size will be used (the image will not be up-scaled), this is not ideal because blank space may appear around the thumb.

If you don’t have the possibility to upload large images you could use a combination of plugins to upscale the thumbs – Thumbnail Upscale and Force Regenerate

Aspect Ratio

There’s no ideal image size, on cropping a part of the image will be lost due to aspect ratio differences, some modules have a 16:9 aspect ratio some have one closer to 4:3.

Example 1:  if you upload an image that has an aspect ratio close to 4:3 the cropping function will cut the bottom on thumbs which have a 16:9 aspect ratio.

Example 2: if you upload a 16:9 image the function will cut a portion from the sides for the thumbs that have an a 4:3 aspect ratio.

Depending on the module used, the best solution is to experiment with different sizes and see which one offers the best results.
