Quilbert, haven't you got a quarry nearby ? It works out much cheaper, our local quarry only does 18 tonne loads at €22 a tonne, we don't need that much but I hide it under hedges etc to re-plenish at later dates, it works out cheaper in the long run as it goes up in price every year.

If Quilbert only needs 64 bags at 25kg per bag then the total weight is just over 1.5 tonnes. This small quantity does not warrant a bulk load. It may be worth while knowing the basic dimensions of the area to be covered and we could all compare our calculations and come to an agreed figure for Q to consider.

There's one not too far away, but I don't think the quantity justifies it and as terrible, indecisive shoppers, the last thing we need now is more choice!

The last time I had to calculate something similar was for our last house in England, where I ended up being out by a factor of 50! Fairly sure I've got it right this time, though. The sides are 4.00, 6.30, 7.70 and 5.00 metres (as I say, an awkward shape), which I make to be approx 33 m2, so allowing for a few stepping stones etc we're saying 32m2, so at 2x 25kg bags per m2 that's 64 bags total. (Probably!)

what thickness are you putting down?

Have you tried something like this ? www.gravelmaster.co.uk/calculatorI know you say you have funny shapes but could you make them up into rectangles on a plan and do multiple calculations. I like your idea of buying a couple of bags first though as that will test your 2 bags per square metre. Good luck !

with the best will in the world I don't get 33m2. 4×6.30 = 25.2m2 7.70×5 = 38.5m2 = 63.7m2
I may have it wrong because I can't see what you see.

Just keep buying a couple of bags at a time until you are happy

LPTA is right.
In very rough terms, and why I think I'm more or less right...
back x left = 5.6.3 = 31.5, or front x right = 7.7 x 4 = 30.8
If you divide into two triangles, calculate the areas and add the results, you also come out to 32/33.

Now that I see that its a perimeter I get 4+6,30+7,70+5= 23ml 23 ÷ 4 = 5.75 5.75 × 5.75 = 33.06m2

Let’s say it is 3cm deep. An area of 33sqm will need close to 1 cubic meter of gravel and that will weigh about 1.7 tonnes. Your 64 bags of 25kg is about 1.6 tonnes. I believe you have the correct quantity.

I calculated that we needed 10 tonnes. The quarry only sold a full load which was 14 tonnes. The driver reversed into the courtyard and did 2 passes tipping gravel as he went.Made life a lot easier for us, with help from a couple of friends we had it spread in about 3 hours.The beer didn't half taste good We did the same for our car park , the driver did most of the work and I just racked it out

Another way of doing it
((5×6.3)÷2)+((7.7×4)÷2)=31.15
Just a bit of fun you understand 😉

Unless you've properly prepared the ground below, expect weeds to come through within two to three years.
