Uneven width stems and hinting

I’m making a very high contrast all-caps font and am wondering about the setting the stem values. If these values are only used for hinting maybe it doesn’t matter too much since this font is intended for display sizes anyways. Would it be problematic if I didn’t include stem any stem values?

The “downstrokes” are technically 220 units wide, but the “upstrokes” are only 10 units wide—crossbars are also 10 units tall. Is it better to go with the smaller number (as shown in my screenshot) despite the huge difference?

As you pointed out, since I sincerely doubt the font is going to be used at small text sizes, you don’t need to worry about hinting at all. So you can set the stems to what makes most sense to you (but you don’t actually need them).

You can add both values. And then you test. But probably it doesn’t matter.

Thanks for confirming! I’m going to omit the stem values since this design isn’t intended for text use anyways. Anything under 72pt begins to push the legibility
