so I received a flyer in the post today from Dominos.

their new King Size pizzas (A.K.A. New York Style) are currently $19.95 with discount code 592206.

whilst a traditional pizza is $7.95 with discount code 539027

the King Size is 40cms, whilst the regular size is 28cms

in area this is 1,256.64cm² @ $19.95 vs 615.75cm² @ $7.95 equals 1.587cents per cm² vs 1.291 cents per cm² respectively (rounded to 3 decimal points).

2 regular pizzas therefore are 1,231.5cm² for $15.90

of course we need to take into account:

Crustage (area that is only crust)

for the king size there is a circumference of 125.66 compared to 88cms for the regular.

if we assume that the width of Crustage (C) is 5mm then the Topping Area (TA) will be:

King size TA = 1,194.59cm²
Regular TA = 572.56cm²

So $ for TA/cm² is therefore $0.0167cm² for a Kingsize and $0.0139 for a regular pizza.

C for a king size is 62.05cm² and for a regular 43.19cm²

Also, we need factor in toppings and their quantity. However perusing the menu indicates that the toppings are quite similar . but I'll leave that to any discussion.

TL:DR - 2 regulars are better value than 1 Kingsize/New York

        But why do they always put the TL:DR at the end of a page of text, that you don't see until after you've read the whole passage????

        • altomic on 19/02/2018 - 13:05

          people get bored half way through and then skip to the conclusion at the end.

          the TL:DR sums it all up.

        • endotherm on 19/02/2018 - 16:13

          @altomic: The point being, if it is at the top before the "short novel" you can determine if it is worth 10 minutes of your life reading through something that might be irrelevant to you, or you have no opinion about or input towards.

        • Question on 20/02/2018 - 21:33

          @endotherm: Learn to speed read dude, you just need to glance over it to get the gist of the post. Try doing the same to a very badly written research journal article that is written by someone who thinks using complicated words makes his article look more impressive. Oh and it doesn't help that they have very little paragraph spacing to save money on printing costs…

          @Question: Thanks for the lesson on how to read, dude. I've been doing it for a long time and can do it quite quickly. Some of us actually respect other people enough to read everything they have taken the time to write. The problem with skimming is that most people reply to a post missing vital details, or missing the fact their question or comment has been answered many times in the preceding posts. The point of my comment was that it seems silly to include a summary intended to help you skip an irrelevant article at the end. Formal reports and letters usually include a prominent subject title/summary at the beginning. Seems like a logical place for a TL:DR. I'm old enough to realise including a TL:DR as an afterthought would be hard if using a typewriter and paper, but in the electronic age, it is trivial to go back and insert it at the beginning.

    I feel that the width of Crustage (C) of 5 mm is too generous, at least from my experience with regular pizzas. I think 2 cm is more appropriate.

    New cost per topping area would be $0.0196/cm^2 (king) and $0.176/cm^2 (regular).

    Either way, regulars are more cost effective (with C = 2, by 11%).

    • ronnknee on 19/02/2018 - 14:15

      Oops, missed out a zero.

    Why are we wasting our time trying to cure diseases and fix global warming when the real problem is inconsistent "crustage"

  • D C on 15/02/2018 - 15:51

    So Dominos reduced the size of their pizzas in order to make the new 'big' pizza look bigger. Hmmm.

    BTW, don't wash you tin foil hat, the fluorides in the water damage it.

  • cloudy on 15/02/2018 - 15:52

    Nice, What do you do for a living? Other than measuring pizza per buck.

  • AdosHouse on 15/02/2018 - 16:00

    The bigger question is, who pays $20 for a pizza for Dominos when there are plenty of premium pizza places where you can get a good pizza for the same price?

      AMEN! The only reason I am all up in Domino's is the price. If I had to pay menu price I'd hunt down a good restaurant

  • dapt on 15/02/2018 - 16:18

    Unless the crustage width is larger than (401/20-3/20*SQRT(7049)) ~ 7.46cm, the classic pizza is the better value in terms of topping. I've seen some pretty bad pizzas come out of these places so that's not completely out of the question.

  • KaTst3R on 15/02/2018 - 16:56

    I'll get a party sized pizza from costco instead.

        Saw that before, same code like last time. Wish for more future PH coupons so I can quit eating Domino's cardboard.
        Btw, I'm just trying to distract OP from calculating a pizza. :P

  • hamza23 on 15/02/2018 - 18:13

    I found it interesting that they advertise New York pizzas as 16" but King Size pizzas as 40cm, initially I thought the King Size would be slightly larger but a quick Google search shows that 16" = 40.64cm.

    You would imagine that might have been the aim, as I can't see why advertising one of your pizzas in inches and the other in cm would be very logical, unless you were trying to make one sound bigger than the other. Also to try and justify the regular price for New York ~$17.95 and King Size is ~$25.95 for the same size pizzas (just more toppings and I imagine might be slightly thicker).

    Ref & Ref 2

    • altomic on 15/02/2018 - 19:09

      even at $17.95 it's 1.43cents per cm²

      or TA @ 1.5 cents per cm² with C at 5mm

  • endotherm on 16/02/2018 - 02:39

    I love the maths, but did you consider the thickness of the crust? Density of toppings? Compare weights? Is the dough recipe different, therefore more expensive (e.g. comparing a nice artisan sourdough loaf to a cheap white sandwich loaf)?

    • kronicmacstigator on 17/02/2018 - 23:18

      His maths is solid. It's Domino's here, not discussing the launching of an orbiting satellite. I dare say it's all the same shit, just a different size.

    • ValueInvesting on 22/02/2018 - 23:18

      Good point. Can compare the Kj rating to get an idea of the topping amount.

      For example:

      Pepperoni NY on classic crust $14.95 (w/coupon) works out to 738.42Kj per dollar.

      Regular $5 pepperoni on classic crust is 1,019.2Kj per dollar.

      Unless you wanted to have the gimmick of a big slice then it's not worth it.

  • kronicmacstigator on 17/02/2018 - 23:19

    Great job :) Plus it's harder to get fat with a smaller pizza.

  • MathNerd on 18/02/2018 - 16:03

    Did you know that if your pizza has a radius of z and height of a, then its volume (assuming it's a perfect cylinder) is:
    V = Π * z^2 * a
    = pi * z * z * a
    = pizza

    Isn't maths just great?

      If that ever worked on a date, you'd probably get a square root afterwards!
