It's a good size to choose if you're planning on using a convertible crib that can later be turned into a toddler bed. Mini crib mattress: This size is ideal for smaller spaces, such as apartments or shared bedrooms. It's also a good option for grandparents' houses or for travel cribs that have a mini size option. Portable crib mattress: These mattresses are specifically designed for portable cribs, which are typically smaller and foldable for easy transport. They have the same dimensions as a mini crib mattress, so be sure to check the label to ensure it's the correct size for your portable crib. Travel crib mattress: Similar to portable crib mattresses, these are designed for travel cribs and have a slightly different size to accommodate the features of the crib.

Measure the length, width, and depth of the crib, and compare those measurements to the dimensions of the mattress you're considering. Consider future use: If you're planning on using a convertible crib, keep in mind that the standard crib mattress size is recommended for safety reasons.
