How much would a 4-inch square serve, assuming it would be cut in the typical wedding cake serving sizes? Also, which cake serving chart do you prefer to use? I have used Earlene's in the past, but I know Wilton's is different than hers. I am just wondering if Wilton's is more accurate.

8 servings... 1" x 2" x 4" (8 cu. in. industry standard). Wilton's chart is the accurate industry standard.

Thank you!

For square/rectangle cakes, its easy to do the math so you can figure the servings on any size cake.

when cutting, for example, a 10" square cake into 1x2x4" pieces, you'd cut one side into 10 rows (10" side divided by 1" cuts) by 5 columns (10" side divided by 2" cuts) = 50 pieces.

A 4" square would be cut into 4 rows by 2 columns = 8 servings.

16" square = 8 rows by 16 columns = 128 servings.

And so on.

oh ok, thanks!
