After years of making stacked wedding cakes, I now have orders for three wedding cakes with pillars. I use SPS so I have no fears of just extending the pillars above the layer for next layer up. But I'm not sure how tall those pillars should be. My cake tiers are 4" tall. Most of the UK pillars (not SPS but sure are good looking) are offered in 3". 3.5" and 4". I figure I can cut my SPS pillars to the desired height..but how much space should be between each tier and still look in proportion? Any experience, insight and suggestions are greatly appreciated.

It really depends on the look you're going for. If you use a 3" space the cake is going to look short and squatty with a triangular or pyramidal shape. Use a 4" space and the cake will have an overall shape more like a Christmas tree. Use a 5-9" space and it starts to look too tall and towering. Personally, I like the mid-range space for most cakes.... at least 4" but no more than 5" whenever possible.

Thanks Unlimited. That makes a good deal of sense. As an update, my cousin in England asked her friend who owns a lovely high street bakery about this and he suggested that when the tier is 4" high, the bottom tier pillar should be 4" and all upper pillars should be 3 1/2" in order to keep the proportions of, as he put it, "magestry". He said English cakes (both fruit and sponge) are usually 3" tall so he recommends a 3 1/2 inch on the lower tier and 3 inch above
