Each listing on PropertyPal has a set amount of space to show the agents logos. Where a logo isn't the same shape as this space, the system will fit it in so that the whole logo shows, and isn't cut off.
The ideal size for your logo is 400 x 160 pixels, or larger, but keeping to that aspect ratio. If you give your designer these dimensions, and ask them to adjust your logo to this aspect ratio, then send us this amended logo, we will upload this to your account for you.
