Hi.
I have exactly the same problem. Currently i am cutting images for a website.
If i save the image (.jpg) and include it in the website, it appears exactly 150% bigger.
See the attached screenshots. First screenshot shows the with zoom 100%.
If i go to View > Zoom > Actual Size the image will be zoomed to 167% but that is not really correct.
When i zoom to 150% the image size is nearly the same as in the browser.
In Photoshop, as the previous speaker said, the size is exactly the size I expect in the browser.
Question: How can I set Affinity so that I can also see the expected size at 100%?
Hint: I use Windows.
