Measure the tabletop separately from the base: record its length, width, thickness, shape, weight if known, and usable underside attachment areas. Add the target finished table height and intended seating layout. These details help a supplier assess a proposed base; overall length alone is not enough to establish compatibility.
Use one consistent set of units throughout the brief. If a drawing mixes feet, inches, and millimeters, label every measurement explicitly. A careful sketch is more useful than a polished image with unclear dimensions.
Begin with an outline of the actual top Draw the tabletop as seen from above. For a rectangle, record both length and width rather than assuming a product description gives the finished dimensions. For a round top, record the diameter. For an oval or irregular top, show the complete outline and the widest and narrowest areas.
A live edge slab deserves measurements at several locations. Mark where the width changes and where a curved edge may affect the overhang beside a chair. Distinguish the overall envelope from the usable area where supports could connect.
If the top has already been fabricated, measure that piece. If it is still being selected, identify which dimensions are provisional and obtain confirmed information before placing the base order.
Record thickness and underside variations Measure thickness where the base might attach, not just at a visually convenient edge. Note any underside recess, apron, bevel, uneven area, or existing support. A thick-looking edge does not necessarily describe the material available at a mounting point.
Photograph the underside in good light. Include a wider view that shows orientation and closer views of existing holes, threaded inserts, repairs, voids, and obstructions. Label the images so the supplier can relate them to the drawing.
Do not drill exploratory holes to complete an inquiry. When a measurement is inaccessible or uncertain, say so and ask how it should be confirmed safely by the appropriate installer or tabletop supplier.
Keep finished height distinct from base height The finished table height is the height of the assembled table. Base height and tabletop thickness are separate inputs. Depending on the connection arrangement, additional components may also need to be considered by the supplier.
Write the target finished height plainly on the drawing. If you are matching existing chairs, include their seat height, armrest height where relevant, and any clearance concerns. A familiar product category name does not replace checking the actual furniture together.
Review NeoSilvan’s table-base buying guide for the relationship between dimensions, seating clearance, and application.
Obtain weight information without guessing Ask the tabletop seller for the weight of the actual top or a confirmed weight appropriate to the supplied piece. If no reliable information is available, state that it is unknown. Do not turn a rough visual estimate into a precise specification.
The supplier may need further information before recommending a base. Photographs, material descriptions, and dimensions are useful, but they are not interchangeable with weight or a suitability review.
For an unusually large or heavy top, arrange handling and measurement with appropriate professional help. The purpose of the brief is to communicate facts, not to encourage moving a slab simply to obtain a number.
Add the seating and floor plan Draw the proposed chairs around the tabletop, including occupied end seats. Indicate the direction in which people approach and pull back their chairs. Mark any floor outlet, rug edge, or nearby transition that may affect base placement.
Then add the proposed base outline or its published dimensions to the same drawing. This makes it easier to discuss knees, feet, armrests, and projecting supports. A plan view is particularly useful for branching or crossed bases whose footprint differs from a simple pair of legs.
The Spider Table Base product page is a starting point for its actual configuration information. Do not transfer those dimensions to another design in the metal table base collection.
Prepare a compact measurement package - A labeled top-view sketch with length, widths, and shape. - Thickness measurements and clear underside photographs. - Actual or supplier-confirmed weight, or a note that it is unknown. - Target finished height and chair measurements. - Intended use, delivery location, and any installation-access concerns. - The exact product or configuration you are considering.
Keep revisions dated. If the slab or chairs change after the first discussion, send an updated drawing rather than relying on an earlier quote to cover a different combination.
Frequently asked questions ### Should I write dimensions as length × width × height? Yes, if each dimension is clearly labeled and the units are stated. Specify whether height describes the base alone or the complete table.
What if my slab is not rectangular? Show the outline and measure at multiple points. Include photographs so the supplier can relate the measurements to the actual geometry.
Can I choose a base without knowing the top’s weight? You can begin an inquiry, but identify the missing information. The supplier may require it before confirming suitability.
Where do I send the measurements? Use NeoSilvan’s Custom Project page. The project-description field can hold your measurements and notes; related product information is retained when you arrive from a product inquiry link.
Good measurements reduce ambiguity. They do not replace product-specific review, but they give the conversation a dependable starting point.
