Toddler bedding tends to come in a fairly standardized size, meant for smaller beds and small children. Some common dimensions you might see for smaller beds may be around:
- Fitted sheet: 28 inches wide by 52 inches long
- Flat sheet: 42 inches wide by 70 inches long
- Pillowcase: 20 inches wide by 30 inches long
- Duvet/Comforter: 48 inches wide by 60 inches long
- Sham: 20 inches wide by 26 inches long
However, some toddler bedding tends to be larger for if you purchase a big bed that the child is meant to grow into over the course of years. These dimensions could be around:
- Fitted sheet: 39 inches wide by 75 inches long
- Flat sheet: 66 inches wide by 96 inches long
- Pillowcase: 20 inches wide by 30 inches long
The important point to keep in mind is to measure the bed you have for your toddler and choose bedding accordingly.
You might also want to make sure where you purchase from has a good return policy. A curious feature of toddler bedding is that the listed dimensions tend to be different. Some may list every piece in the set, others may list a few and some only list product weight. You may just need to try the bedding on the mattress and set how it fits. Sheets should fit snugly over the mattress without being a struggle to get on and bedding should not touch the floor as it hangs down.
As a side note, it's also important to consider what is included. Some products could be a full bedding set like the first list of dimensions above or others might include a few items.
