Hi, I'm starting this thread to see if there's any interest or use to anyone to have a sort of database of diapers with objective measurements how big in which direction diapers actually are. Not how well they fit, feel, look, absorb, etc. things that are more or less subject to opinion. Only things that are objectively measurable or discernible. For a reference, I took everyone's favorite (that's a hyperbole), the revered NorthShore MegaMax in size L which I will post as a first practical example. Standardized content format, in my opinion, would be best that starts with a headline: brand, type and size, then a picture with dimensions, and then a bulleted list of properties and features. See below ______________________________________ Brand and Type - Size (Picture with dimensions in centimeters goes here. Centimeters because SI (metric) is the superior measurement system, get over it, it is the system of science and this is meant to be scientific. For measurement, diaper should be placed at a reasonably flat surface and fully spreaded, but not overstretched. Specs and features: Rated ISO Capacity: number in mililiters Rated waist circumference: range in centimeters (inches in parentheses, because converting this is not that much extra work and many manufacturers state it in inches anyway) Backing material: polyethylene foil OR non-wowen fabric (alternatively plastic or cloth-like, but note that not all non-wowen fabrics are made equal ... Seni and ABU are of different kind than others) Base color: base color of the backing Print: landing zone OR full OR none OR stock (stock means full legth pattern stripe typical for medical diapers, sometimes with drop symbols, size letters etc.) Relative thickness: + OR - OR ~ (with Mexamax as a reference, + for thicker , - for thinner than, ~ for comparable) * Tapes: number of tapes on both sides, simple adhesive OR stacked adhesive OR hook-and-loop OR single combination OR stacked combination Landing zone: adhesive refastenable OR hook-and-loop OR none; width, height, offset from top in centimeters Elastic waistband: front only OR rear only OR front & rear OR none Standing leak guards: yes OR no Wetness indicator: yes OR no Soak pad: yes OR no Scented: yes OR no (* relative thickness to Mexamag (the reference). Measurement should the thickness of a diaper at the highest point (typically in the middle) that has been taken out of a package but has NOT been unfolded yet, and let sat for > 12 hours on a flat surface with no weight on top of with, and also measured without any pressure acting upon it. Why? Well, measuring thickness whilst inside a package is not informative, because diapers are heavily compressed to fit in. It should be not unfolded, because unfolding and refolding will completely skew results. And why relative and not actual number? Because in this case, number doesn't mean that much. Measurement in this dimension introduces a lot of variables that are difficult to control, so a Megamax L that has been taken out of a pack and let sit for some time is about 4.5 cm thick. A diaper that is within +/- 5 mm of that should be ~, otherwise + for thicker or - for thinner. Now, the point of this all might be, that if someone is trying out some type of diaper, but feels that it could do with few centimeters (inches) more or fewer in certain directions, could look into this, and find comparison. See, manufacturer numbers for waist circumference, let alone the S, M, L, XL, L/XL and other designation are not always comparable, all manufacturers have their own ideas of how actually large should a "Large" be, and sometimes, you even find variances between products of the same company. ABU is guilty of this, where their size Large Space is bigger than most other size Large diapers, Betterdry XL is shorter in length than size large Crinklz (same company), and lots of other shenanigans. So, enough yapping, here's an actual example: NorthShore Megamax White - L Rated ISO Capacity: 6500 ml Rated waist size: 107-137 cm (42-54") Backing: polyethylene foil Base color: white Print: none Relative thickness: = Tapes: 4, simple adhesive Landing zone: adhesive refastenable Elastic waistband: front & rear Standing leak guards: yes Wetness indicator: no Soak pad: no Scented: no Some commentary about the dimensions, because there are curves between the crotch and wings, the distance between front and rear wing (32 cm) is taken between the apexes of these curves. Otherwise, it's (I hope), quite clear. Measurements should include overall length (99 cm), wing width (77 and 77 cm, can differ depending on type), wing height at edge (17 cm front, 24 cm rear), crotch width at middle (35 cm), padding height (79 cm), padding width at front, mid and rear (30 cm, 21 cm, 36 cm), padding hourglass height (18 front, 24 rear), tape width (4 cm). Elastic waist band widths (front 24 cm, rear 25 cm) are optional. They introduce sort of a variable as they stretch (that's what they're for after all), and some diapers don't have them usually on front, or at all. I would very much appreciate your feedback, ask questions, have suggestions, and if there's enough interest, I'll get to work measuring and posting shortly (well, in about a week and a half - I'll be out of town for some time), and I would like to ask admins if it would be possible to perhaps eventualy pin this thread, if it gains traction. Thanks

I seem to see a lot of medium/small diapers in daily diaper pictures and myself being right on the border of medium (46 inches) has made me a little self conscious since I ether have to wear sagging large diapers or cram into medium diapers. But I've notice some have been mentioning they wear l4's and I'm curious to see where the diaper community in terms of sizing for your diapers fall. This is only a rough estimate in terms of sizing but I appreciate your feedback. Thanks!

I have recently tried my samples of ABU Preschools, I had a sample of both the small and medium size as my waist measurement is at the top end of one and the bottom of the other with the small both sets of tapes where either on or near the edge of the landing zone and the waistband sat just over my belly button, with the mediums the lower tapes where towards the outer whereas the upper tapes met in the middle with and inch or so of plastic above my belly button. Around my legs I cannot say I noticed much difference but the smalls where abit tighter at the top of my thighs. In this situation where one is between sizes is it better to go up or down or does it not really matter?

Hey everyone! So recently, i've been interested in buying a onesie, but i'm not sure which one I should get especially since i'm pretty tiny (5'6 , 132lbs). I want to get one that has a snug fit and keeps my diaper from sagging. I recently came across the Blue Dinosaur Onesie made by the company Baby Pants but i'm not sure which size to get, and the whole measuring your body thing confuses me >.< . I was hoping someone could give me advice. That would be great! Thanks!
