# The Gust of Wind spell creates a 10-foot-wide line of wind originating from the caster; how do I center it on a 5-foot grid?

Characters are on a grid where every square is 5 feet on each side.

The description of the gust of wind spell says:

A line of strong wind 60 feet long and 10 feet wide blasts from you in a direction you choose for the spell’s duration.

How do I center a 10-foot-wide line originating from the caster on a grid made out of 5-foot squares?

• Am I correct in assuming the basis of your confusion is that a Small or Medium caster would occupy 1 square on the grid, and so literally centering the origin of the line on the caster would cause the AOE to not align to the grid? (That is, say that you're looking at columns A, B, and C; the caster's in column B, and aiming toward the top of the map. If you literally centered the 10-ft-wide line on the caster, the spell's area would cover full squares in column B, but also cover half-squares in both columns A and C. Are you asking if that's the correct/intended method to adjudicate this?) Nov 4, 2020 at 1:11
• Yes this was my question but Thomas already explained to me Nov 4, 2020 at 12:06
