Base profile
The size of the main parts of the table base in a section, in other words, the thickness of these parts. A larger profile, on the one hand, has a positive effect on strength and massiveness (see "Weight"), on the other hand, it affects the cost. Manufacturers select this parameter in such a way that the base can at least normally withstand the weight of the countertop; and since advanced models are equipped with thick and, accordingly, heavy countertops, their base must also be strong. This means that a large profile is often (though not always) a sign of a high-quality table.
Edging height
The size of the edging (usually metal) attached to the edge of the table is the size in height, taking into account that the table is unfolded.
The edging provides protection to the tabletop, protecting its edges from chips and cracks when in contact with surrounding objects (for example, when transporting through a narrow doorway). In general, the size of the edging is a purely reference parameter — usually, it significantly exceeds the thickness of the countertop, which is quite enough to perform the main function.
Weight
The weight of a tennis table is, to some extent, an indication of its overall class. A more advanced model, usually, also weighs more: it has a thicker tabletop, and a more solid base, such a table is more stable and harder to move. Among models for indoors (see "Type"), weight up to 70 kg is typical for amateur tables, from 70 to 110 — for semi-professional, and above 110 — for professional. The weight of all-weather tables can vary from 40 to 100
