It is not difficult to stretch a leather case

How to stretch a leather case

A leather case that does not fit on the phone or fits too tightly, causing the buttons to operate, it is advisable to enlarge it a little. The leather stretches well if it is wetted with water, and when dried it retains its given shape, so use a simple method.

  • Try to select or cut a piece of wood that is the same size as the mobile.
  • Split the resulting workpiece in half along the flat side. Insert a thin plastic plate into the slot.
  • Wet the cover well in warm water and stretch it onto a wooden model.
  • Leave it to air dry without heat, otherwise the leather will dry out and crack.
  • After about a day, when the cover is dry, remove the plate, and then the wooden block.

The accessory will stretch to the desired size. If you use a mixture of alcohol and glycerin instead of water, the drying time will be reduced, the procedure will be more gentle on the skin, and the surface will retain its shine.

How to stretch a silicone case

Silicone is a fairly durable and elastic material. There are many covers available from it, so you can always choose the right option. If desired, buy an accessory - a bumper, which is easier to put on and does not require selecting the location of the connectors.

But there are still times when it is necessary to stretch the silicone case. You can do it like this.

  • Considering the property of silicone to stretch over time, you can crush it with your hands and pull it to the sides. If the size does not fit just a little, you will soon be able to put it on.
  • After heating, the silicone becomes more flexible, and it is easier to pull the case onto the phone. You can use a hairdryer here.
  • If there is a large difference in size, stretching on a wooden model is suitable. The cover must be heated in hot water, pulled onto a prepared block, heated for an hour in water and cooled in air. The disadvantage of this method is that the silicone can stretch too much and will dangle on the phone.

The cell phone case is a little inappropriate in size. How to stretch it?

    My cell phone case didn't fit a bit. That is, the mobile phone fit in there by tension. At the same time, the buttons turned on and the display lit up. I solved this problem by wrapping the phone in paper and putting it in a case overnight. You can add paper as you stretch the cover and increase its size. After two or three weeks the problem was resolved.

    To stretch a leather case, make a model of your phone from a piece of wood (the thickness should be slightly thicker than the phone), split it in half lengthwise and insert them into the case. Between the halves, insert a plastic insert of the thickness to which you want to stretch the phone and put it in a jar of warm water for a day (you can put the jar on the battery). Remove the case from the water and air dry.

    Alternatively, instead of water, you can use alcohol to significantly reduce the drying time.

    Why a tab? Because after drying, the cover can compress the model so much that it will be impossible to remove the piece of wood. In addition, the tree will also swell from water. And plastic, even sandwiched between pieces of wood, can easily be pulled out. Just remember to make the insert long enough so that you can grab onto it later.

    Don't want to bother with making a layout? There is an easy way, but the quality is not guaranteed.

    Just insert pencils, felt-tip pens, round rods, etc. inside the case along the edges. of the appropriate diameter, and push a rectangular piece of a suitable size between them with tension. The rest is the same as described above.

Not all cases fit the phone equally well. Many users are faced with the problem that the dimensions of the protective accessory do not match the actual dimensions of their device. For some, the gadget falls out of the case, for others, on the contrary, the case turns out to be much smaller than the device. Today RosCase will tell you how to deal with such problems, how to make a silicone phone case smaller or larger.

First of all, we want to protect you from such situations. Our main advice is not to buy the cheapest product from a dubious seller. A low price may mean that the materials used in the manufacture of the product are not of the highest quality. Therefore, full compliance with the high user requirements can be left as a wishful thinking. If the plastic case does not fit tightly, you can always try to return it to the seller.

It is much safer to choose accessories from well-known brands and carefully study the characteristics of the case before paying for the purchase. Trust our many years of experience - branded accessories are made with much greater care. The materials used are proven, and the dimensions are precisely adjusted to the dimensions and functional features of a particular device. Our website presents cases from such well-known manufacturers as Rock, Nillkin, Tetded, Nuoku, Mercury, etc. And all their sizes are ideal for the specified device models.

If you have already become the owner of a would-be case, first of all you can try to return it back to the store, based on its inconsistency with the specified model. Only if you fail to do this can you proceed with independent procedures and subject the case to various tests. After all, there is nothing left to lose.

What kind of aids for changing sizes are recommended on the Internet: hair dryer, alcohol, freezer, boiling water, acetone, even a microwave oven. We tested, in our opinion, the most adequate method - and we managed to shrink our experimental sample by a few millimeters.

So, for our experiment we needed the cover itself, a stove, a saucepan, and water. We boiled water and lowered the cover into it for 7 minutes. While the cover was cooking, hold it with a spoon so that it does not float up. After undergoing the rejuvenating procedure, the accessory went to cool down. When its temperature dropped to normal, we tried it on our smartphone - the case no longer fell off and fit tightly.


Let us clarify that our case was made of opaque silicone. This method has a very ambiguous effect on transparent cases, turning the transparent material into a matte one. Well, if the color of the case is not important to you, but its functionality is important, this is unlikely to stop you. But, in turn, we warned you. Having also conducted an experiment with several more pads, we came to the conclusion that not all of them reacted with compression to bathing in boiling water. Some remained larger than necessary in size. From this we concluded that this method is not suitable for every case, but you can still change the size of the silicone case. Unfortunately, you can find out whether this method is effective for your case only by conducting a similar experiment yourself.

How to solve the problem of enlarging the case

As for tips on how to stretch a leatherette phone case, slightly different approaches are used here. We all know that skin tends to stretch. Good leatherette also provides similar opportunities. By analogy with natural material, you can try to stretch the case by inserting a model of your device into it, for example, made of wood. First, the base must be split in half, installing a spacer in the center, which will increase the capacity of the case.

Experts advise placing this entire structure in warm water and leaving it for a while. After the spacer is removed and the case is dry, it should acquire a new desired shape that will allow it to be easily installed on the gadget.

Do not forget that before trying this method, you should, again, contact the seller and tell him your complaints regarding the defects of the ordered product.

Summarizing all of the above, we want to say that it is still possible to return the shape of a deformed phone case. But not everyone. Therefore, before purchasing protection for your device, make sure that it is perfectly compatible with your device by requesting information from the seller. Then, if the slightest discrepancy arises, you will have a reason to return the case, and not look for ways to change its size. Have a nice case!

Then most likely you purchased a low-quality accessory from a dubious seller on an advance payment or received such an unpleasant surprise included with a smartphone from China.

Although this is not pleasant, you can still try to restore the silicone case. Why try? Yes, because it is not known how a particular cover will behave during heat treatment, and yet some bumpers can be restored in size and bent edges corrected.

It is worth immediately noting that in this article we are talking about covers made of thermoplastic polyurethane (TPU), this is the main material for the production of bumpers today, however, there are other material options, and it is difficult to predict how they will behave when processed in this way.

Restoration of shape by thermal method

Most often, this kind of deformation and stretching occurs when the covers are transported carelessly or when stored in improper conditions without a special damper insert. Such cases take an irregular shape and do not fit tightly on the smartphone. However, if such an accessory was made exactly to size, this can be corrected.

To restore the cover, we need two containers of water; it is very important that the size of the containers used is larger than the size of the cover itself. If you place the case in a small container, you risk deforming the accessory even more.

In the first container, you need to bring the water to a boil and leave it on low heat, and in the second, the water should be as cold as possible.

Dip the stretched cover into boiling water and hold for up to 5 minutes (time depends on the thickness of the cover). After the cover has warmed up well enough, transfer it to cold water, and if there are any deformations on the edges of the bumper, straighten them with your hands and in this position lower them into cold water.

Such a sudden change in temperature can cause a slight decrease in size, but if the case has a significant deviation in size, you most likely will not be able to reduce it.

How to buy a quality case?

Defects in accessories happen in any store, even the most famous ones, but the approach to solving the problem is the hallmark of good stores.

If you are forced to choose a case online and are unable to try it on and hold it in your hands before purchasing, you can always use the cash on delivery service. This service is provided by most delivery companies in Ukraine. And suspicious sellers who refuse to send you goods in this way should immediately arouse your suspicion.

Most likely, they are selling a low-quality product and are afraid that you will refuse it.

It often happens that it is not profitable for you, as a buyer, to pay the cost of delivery, and even the cost of the cash on delivery service, but the online store site meets you and pays for the delivery of any goods at its own expense. You can order a high-quality cover at a very inexpensive price, try it on at a Nova Poshta branch before paying, and at the same time not overpay inadequate amounts.

Return or exchange guarantee

A money-back or exchange guarantee for defective goods can be very useful, most good stores are required by law to adhere to this rule and provide you with such a guarantee for a period of 14 days. However in the online store website such a guarantee is as much as 25 days! This is an opportunity to test the product in practice, without risking losing your money.

Please note that unscrupulous sellers also write about this guarantee, but they use free ad services and one-page sites to distribute their goods, since you will not be able to check reviews about such a seller or complain anywhere.

When choosing a reliable store, pay attention to the presence of a real address, reviews using authorization through social networks and high-quality advice on the issue that interests you.

Ask if you can come and see the product at the specified address? If the seller refuses to show you the product and insists on sending it with advance payment or partial payment, he is most likely a scammer.

Our online store also has a channel on YouTube, and you can see what the type of case you are interested in looks like.
