Lettering and strokes??

[CustomSigns&Mailbox]

I am new to making signs , and i am quoting a project, the specs call for 4" letters with 1/2" stroke, (wordage is "Firewall-Do not penetrate") 2 lines how do i figure out the overall size of the sign?

I need direction as to how to fabricate.

Thanks

Just type it out. Use a highway font C and 4" is almost a .5 stroke already. So at 4" letters on two lines it's about 44" wide. by 11 or 12 tall depending on the spacing between lines.

Find a sans serif font that has 1/2" strokes and type it out.
I recommend a condensed font.
