Average height and weight?

I'm not sure that there can be a generic table for all children.
It partly depends ethnicity, as it does for adults.

Probably should have said "white, British" child of a given gender and age. Thanks Ilovecheese

Have you tried the NHS website?

Dress pattern websites will have charts will giving average measurements, but not weight and height, i don't think. How about trying physiology websites?

Maybe this request is regarding your GD who must transfer a distance to a 'bad' school? If so, and she was small at birth, perhaps look for low birth weight charts. I believe there are some that further extrapolate from birth. Some of my GC are very small, I have seen their mums bring home information from routine visits.

World Health Organisation (WHO) may have something.

My DGD was not small at birth Norah she was average birth weight. She is just very small for her age.

I really need something official from the NHS or World Health or similar if possible.

This comes with a warning that it should only be used by qualified healthcare professionals gilly so if you are concerned about one if your DGCs you should really get in touch with the school medical service or the GP practice.

Is this any use.

link dosen't work but I'm sure you can find the page.

Is there such a thing as an 'average' child at any age, when talking about height and weight?

When comparing children and making judgements about height and weight, the authorities usually talk about what percentile a child falls into. DGD falls into the 9th percentile for height, in other words she is taller than 90% of other children of her age, so is considered tall for her age.

I would think that you would need to look at what percentile your DGC falls into for height and weight and if it is well below the 5th percentile the child would be considered short or underweight, depending on what result you got.

Try your child's health visitor office
They are always good to have on side
The can offer credible opinions to school authorities etc

There are charts giving the percentile of your child and what they think they should be at a certain age.

DD was told that very skinny DS was overweight for his age (105% percentile) until she pointed out that he was 110% for height as well.

I don't know if this is it, can't see too well even with reading specs:

When is her birthday gillybob?

If she is a late summer baby that could be taken into consideration too.

Jalima, we had that problem as well.

The medical record book that people used to be given on a baby's birth has charts for both weight and height ranges up to the age of twenty.

So, yes, the NHS website might be a good place to look.

I have looked at the chart for which you have kindly provided the links janeainsworth and jalima1108 but I don't understand how to interpret the lines going across the graph. Obviously the age. And weight are clear but what do the lines mean ? Could anyone explain to me please?

My DGD was 11 in March this year Jalima1108 so not a late summer baby.

We have a letter from her GP confirming her actual weight and height Cherrytree it also states that she is small for her age but does not offer any comparison. For example letter says she measures 130cm which is small for an 11 year old girl but does not state how small (forgive me but I'm hopeless at explaining myself) I mean is she 2-3 cms smaller than average or 10cms smaller than average? GP said she is probably around 14cms smaller than average but did not state this in the letter. We had to pay for the GP to write the letter and it has taken believe it or not 3 weeks so can't ask for another one or we will miss the deadlines.

Probably all a waste of time looking at the figures for appeals at the school anyway.

To me, the pink lines, going left to right, seem to say that your DGD is in the 2nd percentile. I don't know exactly what that means, but you can see it is several lines below 25% (where 75% of the girls are taller).

Not to insult: Do you mean, how to follow the pink line? I believe the point where the age, height and pink line intersect is your answer, with the % to the right edge as the pink line climbs the chart. Make sense?

Um, I've not used one gillybob; perhaps if you print it off it could be easier as you could draw the lines in and work it out.

If there is a health visitor involved with the panel they could interpret the results accurately.
Here's a fact sheet which may help:
www.rcpch.ac.uk/system/files/protected/page/2-18%20Fact_sheet_v8.pdf

I would think you need an explanation about the meaning to the numbers to the right of the chart (but inside the chart). Those are the percentiles, but I don't understand .04, 2nd, 9th - I do understand 25th etc. Clearly your DGD is tiny in the 2nd - but 2nd means nothing to me, other than smaller than 25th.

I think you plot where she is on the graph according to height and age then it should tell you which percentile she is in - 50th being average I think. Perhaps someone else will correct me if that is wrong.

I must be really thick and still don't "get it" . The GP did confirm that DGD is " small for her age" the letter states this clearly but I would like the panel to understand exactly how much much smaller she is than her peers. The GP said she is around 14cm smaller than "average" but does not state this in the letter.

Does the percentile mean "this many children will be " etc. again

No, percentile means that with any group of kids the same age, the range of sizes is as stated within the percentiles. A tall child might be at the 80th percentile for height. A small child perhaps at the 25th percentile.

Likewise for weight.

So if a child is at, say, the 50th percentile for height but the 90th for weight, it's quite likely that they're overweight. Or if at 50 for height and only 20 for weight, they,d be underweight.

It's a very rough guide.

Minibags was around the 75th percentile for both height and weight all through her childhood.
