There’s no specific limit to how big a CV should be.
The typical file size for a 1–2 page CV is below 300 KB (saved in PDF format). Unusual fonts, style graphics, and images (such as infographics) can cause your CV file size to be larger than normal. The maximum CV file size is 1–2 MB.
It’s vital to check the job portal’s file size limits before you write your CV and upload it.
You should also consider compressing your CV when sending it as an email attachment if you’re worried employers won’t be able to open it quickly.
