The size of your welding table should match the space you have available and the projects you plan to undertake. A good starting point is a table that is 3 feet wide by 5 feet long. This size is large enough for most projects but still manageable in a smaller workshop. If you’re limited on space, consider building a table that can fold down or is on casters for easy storage. Remember, the height should be comfortable for you to work at while standing or sitting on a stool.
