Let's look at your sentence and fix it step by step:
Your sentence: "We normally use an artboard size +30% of the page make-up (see the layout), which makes the final artboard size (bleeding included): 1453Ñ…249"
To make it clearer and grammatically correct, we can say:
"We normally use an artboard size that is 30% larger than the page layout (see the layout). This means the final artboard size, including the bleeding area, is 1453 by 249."
Explanation:
- "+30% of the page make-up" is a bit unclear; saying "30% larger than the page layout" is clearer.
- "which makes" is changed to "this means" to connect the cause and result smoothly.
- "bleeding included" is better as "including the bleeding area" so it's clearer.
- Use the word "by" to show measurements (1453 by 249).
So, the corrected sentence is easier to understand and grammatically correct!
