1.7 vs 3.4 oz Perfume, Which Is Better for You?

Deciding on a perfume bottle size can truly be daunting. There’s a lot to consider, like the price and how long the perfume will last. So which one is better?

When it comes to perfume, only you can determine which bottle size is better for you. If you will wear this fragrance regularly, then the 3.4 oz bottle would be more cost effective. When you’re planning for occasional use of a scent, then the smaller bottle might actually be more cost effective because there’ll be less waste.

This post will guide you through sorting out the possibilities in order to determine which bottle size would be better for you.

1.7 vs 3.4 oz Perfume

How Are 1.7 vs 3.4 oz Perfume Bottles Different?

So, should you get the smaller bottle or the one that’s twice its size? Let’s first consider some differences between the two.

Perfume Quantity & Number of Sprays

The larger bottle, in this case, 3.4 oz (100 mL), is exactly twice as big as the smaller, 1.7 oz (50 mL) container. 

In the first one, you can expect to get 1000 sprays of perfume, and just 500 sprays from the 1.7 oz perfume bottle.

As mentioned here, a 1.7 oz (50 mL) bottle of perfume can last about 167 days if you spray three squirts once per day. 

So the 3.4 oz (100 mL) perfume bottle can last close to a year, for a total of 333 days, if you press the atomizer down three times within one day. 

Perfume Price Differences

In terms of pricing, there seems to only be a slight difference between the two sizes. But the amount of time that the perfume’s been on the market sometimes factors into the price difference.

Considering the classic and timeless fragrance, J’adore by Christian Dior, there’s a $30 dollar price difference between the 3.4 and 1.7 oz bottles. This seems to hold true with other Christina Dior fragrances, like Miss Dior, as well.

There’s a $42 dollar difference between Lancôme’s 1.7 and 3.4 oz bottles of the earthy yet glamorous, La Vie Est Belle.

But an older fragrance by the same company, the intriguingly complex La Nuit Trésor, only has a $26 dollar difference between the two sizes. 

These are pretty nominal price differences that companies choose in order to nudge you towards buying the larger bottle. Some customers might think, “Well, it’s only $25 dollars more for TWICE as much perfume.” This minor difference can lead you to think you’re saving, even if you aren’t based on your personal circumstances.

Perfume Bottle Design Differences

Sometimes customers select a bottle size based on its design. Companies have been known to make larger bottles more attractive to customers. This encourages them to purchase at a higher price point. 

Considering the brands mentioned above, J’adore by Christian Dior bottles look exactly the same in both 1.7 and 3.4 oz sizes. 

But I notice a slight difference between the bottles of La Vie Est Belle by Lancôme. The 3.4 oz bottle is more aesthetically pleasing to me even though it’s designed in the same way as the 1.7 oz container.

Made of frosted glass, you can see that the light pink liquid is part of the overall design composition. It adds dimensionality. For me, the 3.4 oz jar is more appealing because the larger quantity of perfume adds more depth to the overall design. Based on this alone, someone might choose the 3.4 oz bottle over the 1.7 oz version. 

Beyond quantity, number of sprays, pricing, and design, the bottle size that you choose largely depends on how you intend to use the perfume. 

1.7 vs 3.4 oz: Choosing the Best Size 

Further consideration is a much more personal process. Only you have an idea of how much you like or dislike a fragrance and how often you plan to use it. 

There’s no wrong answer here, just the answer that works best for you. Here are some questions to think about.

Have You Tried This Scent Before?

As you may have read in this previous post one perfume fragrance can smell differently on every person that wears it. We each have our own scent. And your body responds to perfume in a unique way. Both factors plus the perfume formula itself, influence the scent you smell when you spray on your perfume.

In addition to that, environmental factors also play a role. If you’re testing a fragrance out in a store, it may smell different on you in that setting versus testing it out at home. 

When inside the store, you may smell other fragrances nearby – whether the scent is from the fragrance counter or a passerby. There might be a rack of newly hung leather purses just across the aisle and that scent can interfere with the fragrance layers of the perfume you’re trying. 

When at home, you have a little more control over the environment. You can test out the scent in a room that hasn’t been recently cleaned, smelling like Pine Sol. And away from freshly dried clothes that smell like fabric softener. Instead, you can find a fairly neutral space within your home to test out the new scent. 

What all of this means is that fragrances that are new to you should be tested out for a while before you can determine the extent to which you like them. 

So as you deliberate between choosing the 1.7 oz or 3.4 oz of perfume, consider how familiar you are with the fragrance. If you haven’t used it for that long or at all in the past, then you might want to purchase the 1.7 oz perfume bottle.

Are You Traveling With The Perfume?

There are international limits on the amount of liquids that you can bring onto a plane with you. 

When going through security checkpoints with carry-on luggage, the total amount of liquids allowed is 3.4 oz (100 mL).

In this case, a 1.7 oz bottle of perfume would be better if you have additional liquids that you’d like to bring with you onto the plane.

Otherwise, the only liquid you would be permitted to bring onto the place is the one 3.4 oz (100 mL) bottle of perfume.

When checking bags, this rule doesn’t apply. But even so you may still want to take the smaller bottle in order to be able to fit additional items into your checked baggage. Depending on your situation, the smaller bottle might be the better choice.

Do You Already Have a Large Perfume Collection?

Do you prefer to cycle through multiple scents? Then you might be better off with the 1.7 oz (50 mL) bottle of perfume.

Smaller sized bottles are perfect for those who regularly like to wear a different fragrance. This way, you can make a small commitment to this new scent while maintaining all of your other options.

And this is actually more cost-efficient for someone who’s constantly trying out new scents.

The $20 to $50 dollars that you save by choosing the 1.7 oz container can be put towards the small bottle of a different scent.

Is This For Daily Wear or Occasional Use?

Another subjective factor is frequency of use. If you know off the bat that you will enjoy wearing this scent daily, or at least on most days, then you might want to purchase the 3.4 oz (100 mL) bottle.

Why not go even larger, you ask? Well, daily use might be contained to a season, depending on the scent. If it’s a fruity floral or airy herbal fragrance for spring or summer, then you may only use it for three to six months out of the year. 

Based on the typical perfume usage of three pumps, you might have half a bottle remaining at the end of spring or summer. 

Perfumes can last for years. But if you think you might want to try a new spring/summer scent in two to three years, then it would be smart to stick with the 3.4 oz (100 mL) bottle. 

You’ll have as much of the fragrance as you’ll need without having to figure out what to do with what remains. 

The opposite is also true. Are you buying this perfume for a special occasion? Is it for a ceremony, or a trip you’re taking during vacation? 

If you have a different daily fragrance and will only be using this new one from time to time, it’s better to buy the 1.7 oz (50 mL) even if there’s only a small difference between prices. You aren’t really saving money by buying the larger one if over time you end up throwing it away with three-quarters of the perfume left in the bottle.

As you can tell, deciding which bottle size is better has just as much to do with size and price as does understanding how you plan to use the perfume.
