Perfume bottles come in many different sizes, with some larger than others. The most common sizes are 1.7 oz and 3.4 oz, but which is the bigger one?
A 3.4 oz bottle of perfume is larger than a 1.7 oz bottle. 3.4 oz is twice as large and carries twice as much perfume. The 3.4 oz is the most common bottle size and is great for your bottles at home. A 1.7 oz bottle is better for when you’re traveling, as the bottle is smaller and will take up less space.
Despite a 3.4 oz bottle containing twice as much perfume, they usually cost only a little more than a 1.7 oz bottle. And besides that, there are many more bottle sizes! In this article, we’ll cover everything you need to know about bottle sizes and which are the most beneficial to get!
How Many Sprays Can You Get Out Of A Fragrance Bottle?
When it comes to the number of sprays you get out of a bottle of perfume, there are a few simple rules.
In general, 1 ml of fragrance will contain 10 sprays. A 100ml bottle, or a 3.4 fl oz bottle, will contain roughly 1000 sprays. With 4 sprays a day, this bottle will last you roughly 250 days.
Lets quickly go over some of the measurements;
- 3.4 fl oz is the same as 100ml
- Fragrances are liquids, so the correct measurement is in fluid ounces (fl oz)
Below you’ll find a handy table with the most common and most popular bottle sizes. Along with the size of the bottle, you can also see how many sprays each bottle roughly contains, as well as how many days the bottle will last you!
| Milliliter (ml) | Fluid Ounce (fl oz) | Sprays | How Many Days It Will Last You |
| 1 | 0.033 | 10 | 3 |
| 1.5 | 0.05 | 15 | 4 |
| 2.5 | 0.085 | 25 | 6 |
| 5 | 0.17 | 50 | 12 |
| 10 | 0.34 | 100 | 25 |
| 15 | 0.5 | 150 | 38 |
| 25 | 0.8 | 250 | 63 |
| 30 | 1 | 300 | 75 |
| 40 | 1.4 | 400 | 100 |
| 50 | 1.7 | 500 | 125 |
| 60 | 2 | 600 | 150 |
| 70 | 2.5 | 700 | 175 |
| 75 | 2.6 | 750 | 188 |
| 80 | 2.7 | 800 | 200 |
| 90 | 3 | 900 | 225 |
| 100 | 3.4 | 1000 | 250 |

| 175 | 5.92 | 1750 | 438 |
| 200 | 6.7 | 2000 | 500 |
As mentioned before, the 1.7 oz and 3.4 oz bottles are the most popular. However, there are many more bottle sizes. Most designer fragrances come in either of these sizes, but there are some outliers. Here are some examples of fragrances that come in different bottle sizes:
- Christian Dior Sauvage comes in 1 oz (30ml), 2 oz (60ml), or 4.1 oz (120ml) bottles.
- Nasomatto fragrances exclusively come in 1 oz (30ml) bottles.
- John Varvatos fragrances come in 2.6 oz (75ml) or 4.2 oz (125ml) bottles.
- Maison Francis Kurkdjian fragrances come in 2.5 oz (70ml) or 6.7 oz (200ml) bottles.
- Giorgio Armani Acqua Di Gio Profumo comes in 1. oz (40ml) or 2.6 oz (75ml) bottles.
Why Does A 3.4 oz Bottle Costs Only A Little Bit More Than A 1.7 oz Bottle?
Any time you go fragrance shopping, you’ll always see that a 1.7 oz bottle is only a little bit cheaper than a 3.4 oz bottle, despite it containing only half the amount of fragrance.
The small difference in price is a marketing trick to get you to buy the larger bottle. Fragrances, and cosmetics in general, have really high margins, so the profit is large no matter what size you buy. With the 3.4 oz costing only a little more but giving you twice the amount of fragrance, most people tend to buy the larger, more expensive bottle.
The cosmetics industry is known for its incredibly high margins. These high margins leave a lot of room for the businesses to play around with the price. This is the reason why they can offer twice the amount of fragrance for only a small price increase.
What this often means for us as consumers, though, is that the larger bottle you buy, the cheaper you’re off. At least, you’ll get the fragrance for a cheaper price per ml. The price per ml is how much money you pay for a single milliliter. To give you an example, let’s take a look at the popular Creed Aventus.
According to the official Creed Boutique website, a 50ml bottle of Creed Aventus costs $325,00. If we divide $325,00 by 50ml, we get a price per ml of $6,50. On the other hand, a 100ml bottle of Creed Aventus costs $435,00. This comes down to a price per ml of $4,35. This is a lot cheaper!
| Size Of The Bottle | Price Of The Bottle | Price Per ML |
| 50 ml (1.7 oz) | $325,00 | $6,50 |
| 100 ml (3.4 oz) | $435,00 | $4,35 |
| 250 ml (8.5 oz) | $670,00 | $2,68 |
| 500 ml (16.9 oz) | $1.055,00 | $2,11 |
| 1000 ml (33.8 oz) | $1.600,00 | $1,60 |
As you can clearly see in this table, the larger the bottle, the smaller the price per ml!
What Is The Best Fragrance Bottle Size For You?
As a general rule, you should always go with a bottle that has a lower price per ml. 100ml (or 3.4 oz) is the most popular choice for a reason. You get a decent price and a good amount of fragrance. If you’re a collector, however, it might make more sense to go for a smaller-sized bottle.
For most people, buying a 100ml bottle is the best way to go. 100 ml bottles will last you a good part of the year and have a very favorable price per ml. These bottles really are your best bang for your buck without committing to an enormously large bottle.
However, there are many fragrance lovers out there that want more than one or two fragrances. If you are growing a collection of many different fragrances, opting for a smaller bottle might be your best bet. The reason why 100ml bottles are so great is that they last reasonably long for a good price. But if you own 25 100ml bottles, then there’s no way you’ll use all of it (or it will take a very long time).
If you go with smaller, say 30ml or 50ml bottles, you’ll pay more per ml, but in the end, you’ll be cheaper out. And with a large collection, there really is no need for the larger bottles, as a bunch of smaller bottles still amounts to a good portion of fragrance.
Lastly, there is always the option to try samples and decants. These are way smaller bottles, ranging from 1ml all the way to 30ml, and these allow you to try out smaller amounts of the fragrance without committing to a full bottle.
