It is a pity that there are no measures in the product description. It is around thirty centimeters high and twenty wide. You have to buy to find out.
I also regret that all bamboo to bees are not drilled (fortunately it was not the case for one or two). A solid bamboo has no interest in a bee since it does not know to lay their larvae.
Otherwise the price is still affordable. Good product that looks pretty solid.
