Growth Rate - Knowledgebase Question

I am planting both a vine maple and a Japanese black maple. The only information I can find describes both as slow growing. Can you please tell me how fast they each will grow per year, on average.

Ultimate growth rate depends upon climate, soil conditions and general care. The nursery industry uses the following guidelines: On the average, trees in the slow-growing category will grow less than 12" per year. Those in the moderate-growth category generally will grow between 12"-24" per year. Trees considered fast-growing will grow 25" or more inches per year. Hope this information is helpful.
