Is there a list somewhere for what the max DIM is on any given box?

[nc-daydreamer]

With all of the confusion and uncertainty over this new dimension and weight requirements and the right option not being available (like a small flat padded)... Someone on another thread mentioned that if the size was entered right, then the option would appear  in the selection list.  So exactly how does someone know what the size is supposed to be?

This got me wondering... Looked and could not find one... is there a table available that list the max weight and size for each box/envelope offered with the different options available to mail it? Hope I am making sense. If there is such a chart, then we all can better judge what we have and opt for the better choice?

Thanks y'all!!

Does anyone know? Or even have a guess? 

Thanks!

I have absolutely no clue what you're even asking. Can you rephrase the question?  

Dimensional weight applies to any package that is over 1 cubic foot (1728 cubic inches) being sent via Priority Mail or Parcel Select Ground.

None of the current free USPS Priority Mail boxes is over 1 cubic foot.  The Regional C box was.

The maximum weight for all USPS services is 70 pounds,  except First Class (13 ounces retail and 15.999 online) and the Regional boxes (15 pounds for the A's, 20 for the B's).

OP is asking about the USPS Flat Rate and Regional Rate Box and envelope sizes that the new eBay label flow uses to determine when to show or not show a shipping option in the label flow.

The answer is - there is no chart.

The data can be gathered from the USPS Store, and going through all the relevant products there one by one (Medium Flat Rate Box 1, Medium Flat Rate Box 2, Padded Flat Rate Envelope, etc), noting the inside dimensions provided for each one, and building a chart.

Can also be determined by trial and error by plugging in various dimensions in the new label flow to nail them down for each box or envelope (I haven't bothered since I don't use the new label flow).

Here is my list of box sizes I've been using for years - most should be correct and may save some legwork.

Box		Dimensions		     Vol(in³)  wt(oz) Max(lb) Dom/Int
------------------------------------------------------------------------------
Regional A SL	13 1/16 x 11 1/16 x 2 1/2	361	n/a	15
Regional A TL	10 1/8 x 7 1/8 x 5		361	n/a	15
Regional B SL	16.25 x 14.5 x 3		707	n/a	20
Regional B TL	12.25 x 10.5 x 5.5		707	n/a	20
Regional C	12 x 12 x 15			2160	n/a	25

Small FRB	8 5/8  x 5 3/8 x 1 5/8		75.3	n/a	70 / 4
Med FRB-1	11 x 8 1/4 x 5 3/4		522	6.4	70 / 20
		11 1/4 x 8 3/4 x 6 (outside)
Med FRB-2	13 5/8 x 11 7/8 x 3 3/8		546	8.1	70 / 20
		14 x 12 x 3 1/2 (outside)
Large FRB	12 x 11 3/4 x 5 3/4		811	9.7	70 / 20

LFR BoardGame	23.625 x 11.75 x 3		833	n/a	?

ODVDS		7 9/16 x 5 7/16 x 5/8
1096L		9 1/4 x 6 1/4 x 2

1097		14 x 11.25 x 2.25		354	6.5	70
1097 duals	29 x 11.25 x 2.25		734     13.25	70
1092		13.175 x 12.125 x 2.75		439	8.1	70
1095		15.5 x 12.5 x 3			581	8.2	70
Shoebox 	14.375 x 7.5 x 5.125		552	5.6	70
Box 4		7 x 7 x 6 (outside)		294	4.45	70
Box 7		12.25 x 12.25 x 8.5 (outside)	1152	11.9	70

1098M		37 11/16 x 6 1/8 x 5 1/8 x 5 1/16       11.2	Triangle
		38 3/16 x 6 9/16 x 5 9/16 x 5 5/16 (outside)
1098S		25 x 6 x 6 x 5 7/8		         6.6	Triangle
		25.625 x 6.313 x 6.313 x 6.063 (outside)

Padded FRE	12.5 x 9  (flat)                ~175?    0.65	70?

In the eBay new label flow, the PFRE max is 12x9x3, and SFRB is 8x5x1 (I think)

Pretty much, you have to round any USPS internal box size dimensions down to the nearest inch and use those (since the flow only utilizes integer inches)

The rest are left as an exercise for the student.

(Note: the box weights listed above may no longer be accurate - that chart was started 10 years ago, USPS has been thinning boxes over the years, and I don't recall which ones were updated.)

The outside box dimensions, rather than inside dimensions, would be used in the calcs determining size limits. It has been my experience that rounding up to whole integers is more the norm across carriers than rounding down, unless girth is used.

My bad - slip of the fingers. Outside dimensions would be used.

Yes they would in a carrier shipping context for calculation purposes, but not in this context. The purpose of rounding down here is get dimensions UNDER or equal to the limits that the new eBay label flow is using to determine whether or not to show a particular package option.

For example, the small flat rate box is 8 5/8 x 5 3/8 x 1 5/8 Sine you can't use fractions in the label flow, you have to round those down to 8 x 5 x 1 in order to be equal to or under the limits eBay is using (unknown if they are rounding down internally or using the fractional numbers, but doesn't matter)

Thank you to all who replied. Very helpful indeed @berserkerplanet , @shipscript , @nobody*s_perfect  - and anyone else who might add something else soon.

It looks to me as tho the PO or maybe eB would have something already prepared along these lines with the new changes, but I guess I'm daydreaming again...

You are correct. Round down to determine a size that qualifies for that dimensional limit.
