Invoice design change width $accountDetails

Hi,
I want to customize my invoice. So I went to advanced settings.

I succeeded in changing the margin of $accountDetails in the code:
{
“stack”: “$accountDetails”,
“margin”: [
60,
0,
30,
0
]
},

But how can I change the width of it?

I have a very long emailname which is now on two lines.

Try something like

    "stack": "$accountDetails",
    "width": 200,

thanks
