It only took me 5 years, but I finally measured the pockets on my table.

9' GC III (RKC mod)
Mouth size....4 1/2"
Throat size....3 5/8"
Shelf depth....1 3/4"

Here's the latest:

Calculate your Table Difficulty Factor (TDF) to determine how tough it plays in comparison to other tables. Only three pocket measurements are required, and you can use the mobile-friendly online tool (created by "Isaac") or an Excel spreadsheet to do the calculations.

jviss - 9’:1.00, 4.98”:0.91, 0.76”:1.04, 1.625”:1.00 - 0.95 (GC I)

Here's the latest update:

Calculate your Table Difficulty Factor (TDF) to determine how tough it plays in comparison to other tables. Only three pocket measurements are required, and you can use the mobile-friendly online tool (created by "Isaac") or an Excel spreadsheet to do the calculations.

very nice, I always had a doubt, I have a 7ft table with tight pockets( 11cm or less).. but I always wonder if it's a good table to practice due to its size

All practice is good practice, IMO.

Dr Dave.... I dont know if this was asked previously, but how do you, or why dont you figure the side pocket into the equation?

Dr Dave.... I dont know if this was asked previously, but how do you, or why dont you figure the side pocket into the equation?
Here is a pertinent quote from the TDF resource page:

When the TDF system was developed, side pocket measurements were excluded to keep the system as simple as possible (requiring as few measurements as possible) while still capturing the most important characteristics of a table. On most tables, it is the corner pocket toughness (and not the side pocket toughness) that dominates overall table difficulty level.

For a comparison of the effects of side pocket and corner pocket difficulty effects, see the effective pocket size resource page.

measured my table today. Its a Gold Crown V tournament edition.

Table Difficulty Factor 1.00

pocket mouth 11.4 cm (4.48 inch) (PSF 1.00)
side pocket mouth 12.5 cm (4.92 inch)
pocket throat 9.7 cm (3.82 inch)
mouth throat difference 1.7 cm (0.66 inch) (PAF 1.02) this makes for 141° pocket facing angle
pocket shelf depth 3.3 cm (1.30 inch) (PLF 0.98)

measured my table today. Its a Gold Crown V tournament edition.

Table Difficulty Factor 1.00

pocket mouth 11.4 cm (4.48 inch) (PSF 1.00)
side pocket mouth 12.5 cm (4.92 inch)
pocket throat 9.7 cm (3.82 inch)
mouth throat difference 1.7 cm (0.66 inch) (PAF 1.02) this makes for 141° pocket facing angle
pocket shelf depth 3.3 cm (1.30 inch) (PLF 0.98)
9 foot table...
FYI, I've added your table to the list.

Thank you for posting,

Here's the latest:

Calculate your Table Difficulty Factor (TDF) to determine how tough it plays in comparison to other tables. Only three pocket measurements are required, and you can use the mobile-friendly online tool (created by "Isaac") or an Excel spreadsheet to do the calculations.

Hey Dr Dave

Thank you for this system. Its at least a frame of reference for pocket toughness if not overall table toughness.

I have a PAF that is not on the list, only 1/8". The pocket is 4" and 2" back is 3 7/8.

After finally figuring out how to do this system of measuring, here are the rest of the measurements. Can you help me finish the score?

Golden West

TSF 9 ft Golden west 1.00
PSF Mouth 4" 1.20
PAF (4- 3 7/8) "1/8 ???
PSF 1 3/8 ???

Thanks. Have a blessed day.

Hey Dr Dave

Thank you for this system. Its at least a frame of reference for pocket toughness if not overall table toughness.

I have a PAF that is not on the list, only 1/8".
Every number is "on the list" in the different ranges. 1/8" is in the <1/4" (less than 1/4") range.

The pocket is 4" and 2" back is 3 7/8.

After finally figuring out how to do this system of measuring, here are the rest of the measurements. Can you help me finish the score?

Golden West

TSF 9 ft Golden west 1.00
PSF Mouth 4" 1.20
PAF (4- 3 7/8) "1/8 ???
PSF 1 3/8 ???

Thanks. Have a blessed day.
I entered you numbers into the online tool and got:

Tom Cruise - 9':1.00, 4":1.20, 1/8":0.97, 1 3/8":0.99 - 1.15 (Golden West)

That's a tough table.

Thank you for posting,
