The perimeter \( P \) of a rectangle can be calculated using the formula:
\[
P = 2 \times ( \text{length} + \text{width} )
\]
In this case, the perimeter is given as 22 inches, and the width is 6 inches. We can denote the height (or length) as \( h \). Plugging in the known values, we get:
\[
22 = 2 \times (h + 6)
\]
Now, we can simplify and solve for \( h \):
1. Divide both sides of the equation by 2:
\[
11 = h + 6
\]
2. Subtract 6 from both sides:
\[
h = 11 - 6
\]
\[
h = 5
\]
Therefore, the height of the postcard is **5 inches**.
