The width for some heatmaps can be set to absolute units. Note width controls the width of the heatmap body.

ht2 = Heatmap(mat2, name = "runif", col = col_runif, width = unit(4, "cm"))
ht3 = Heatmap(le, name = "letters", col = col_letters, width = unit(5, "mm"))
ht1 + ht2 + ht3

If width is numeric, it is converted as a null unit.

ht1 = Heatmap(mat1, name = "rnorm", col = col_rnorm, width = 6)
ht2 = Heatmap(mat2, name = "runif", col = col_runif, width = 4)
ht3 = Heatmap(le, name = "letters", col = col_letters, width = 1)
ht1 + ht2 + ht3

heatmap_width also can control the width of the heatmap, but it is the total width of the heatmap body plus the heatmap components.
