How to Keep a Slim Profile with Ultra-Thin Mobile Phone Cases and Covers

The term 'ultra-thin' is a qualitative description for slim and/or fitted mobile phone cases. Such cases are designed to add as little bulk to the phone as possible. Ultra-thin cases typically fit closely around the phone and are made from flexible materials such as silicone or rubber. A steady reduction in phone weight since the smartphone revolution of the late 2000s has led to a sharp increase in the demand for ultra-thin mobile phone cases and covers.

About Ultra-Thin Mobile Phone Cases and Covers

Although the mobile phone was invented in the 1970s, it did not reach mass popularity as a communication device until the late 1990s. During this period, the demand for phone covers was low as most phones were either too expensive or sturdy enough to handle accidental falls. Most available phone covers were made from heavy-duty, costly materials like leather. Weight and thickness were non-concerns as most phones themselves were large and heavy. The smartphone revolution of the late 2000s, beginning with an array of touchscreen smartphones, caused a huge increase in the demand for functional, yet aesthetically pleasing phone covers. Retaining the phone's original hardware flourishes and profile became a necessary requirement in phone covers. Consequently, covers and cases made from rubber, silicone, neoprene, etc. that covered the phone like a glove surged in popularity. Ultra-thin covers provide relatively low protection against accidental falls. Yet, they help in retaining or even emphasising the phone's aesthetics and can be made very cheaply. Since such covers are made from extremely thin materials, they add very little weight or bulk to the mobile phone.

Buying Ultra-Thin Mobile Phone Cases and Covers

Ultra-thin mobile phone covers are available in an assortment of designs, colours, and finishes for most popular mobile phone models. Neoprene, rubber, and silicone are the materials commonly used, though plastic is also a popular option. Ultra-thin cases and covers are available in both generic and branded varieties. Due to the variety of available options, a number of factors must be considered before buying any ultra-thin case or cover.

Types of Ultra-Thin Mobile Phone Cases and Covers

The two defining characteristics of ultra-thin phone covers are low weight and a slim profile. A number of case-types meet these requirements. The advantages and disadvantages of these case-types can be seen as follows:






Most ultra-thin cases and covers fall under this category. Fitted and skin type cases fit the phone like a glove and are usually made of silicone or rubber.

Fitted cases provide a very close fit with enhanced grip. They are also low in weight and thickness.

Provide very little protection against tumbles and falls.


A simple pocket made from leather, synthetic leather, or neoprene. Pouches and sleeves can be made very thin at the cost of protection.

Provide a good mix between protection and portability.

Pouches/sleeves are not as slim as fitted/skin type cases. The phone also needs to be removed from case to be used.


Wallet/flip type cases cover both the front and back of the phone. The front can be flipped open like a wallet to access the phone. Some wallet/flip type cases are designed to maintain a slim profile.

Wallet/flip type cases offer strong protection and functionality. They are also aesthetically appealing.

Can add considerable bulk and weight when made from materials like leather and suede leather.

Materials Used in Ultra-Thin Mobile Phone Cases and Covers

The material used to make phone covers must meet a number of requirements. It must be relatively tough, affordable, lightweight, and easy to work with. Consumer demands mean that the material must also be able to accommodate a variety of design and colour types. For ultra-thin phone cases, weight and thickness are two primary concerns. Because of this, the following materials are most commonly used to make ultra-thin phone cases:






A tough, flexible synthetic rubber made from chloroprene, neoprene is widely used to make phone covers and sleeves, dry suits and automotive material.

Neoprene is durable, flexible and extremely easy to work with.

Cheaper alternatives to neoprene exist for making phone cases.


Silicone is a synthetic polymer compound that exhibits rubber like qualities. It is the most popular material for making skin-type phone cases.

Silicone is cheap, easy to work with and offers high durability. It also has properties like heat-resistance, low chemical reactivity, etc. Silicone also stops microbial growth.

Can appear aesthetically displeasing; not as tough as neoprene.


Rubber is a natural polymer widely used for making phone cases, especially for sports and outdoor use.

Rubber is tough, flexible, and affordable. Enhanced grip makes it a favourite for sports-oriented cases.

Rubber is limited by design and colour options. It is also more expensive than silicone or neoprene.


Nylon and polyester are chief among a range of synthetic fibres used to make mobile phone covers.

Synthetic fibres are strong and durable. They can also be woven into a range of colours, designs, and shapes.

These fibres does not offer as slim a profile as rubber, silicone, or neoprene.


Hard plastic can sometimes be used to make shells and fitted cases.

Plastic is tough and can be made into a variety of design and colour-types.

Hard plastic is quite bulky and can add to the phone's thickness and weight.


Vinyl or PVC is commonly used for making ultra-thin skin and fitted mobile phone cases.

Durable and flexible, vinyl can also be printed upon, making it possible to produce a variety of designs and styles. Vinyl is also very thin and lightweight.

Vinyl offers very little protection. It is also more expensive than silicone.

Ultra-Thin Mobile Phone Cases and Covers Designs

Ultra-thin phone cases made from synthetic materials have the advantage of being available in a wide variety of designs and finishes. Different manufacturers specialise in creating phone covers catering to different demographics. Some brands are geared exclusively towards younger crowds and make designs that reflect their audience's tastes. Others utilise more distinguished, plain colours and finishes meant for older buyers. Broadly speaking, the range of designs and finishes available for ultra-thin mobile phone cases and covers can be seen as follows:


These covers are typically made from hard plastic or silicone and have a glossy sheen. Glossy covers are typically low cost and cater to younger buyers.


Metallic covers mimic the lustre of brushed/polished metals. These are usually made from plastic.


Any cover with encrusted jewels is considered under this category. This includes covers with glitter and artificial gemstones.


Covers with a range of prints are a popular option. These are usually made from vinyl, silicone and plastic. Some manufacturers allow the buyer to make customised prints.


Covers in solid colours without any design flourishes are considered under the plain category.

Ultra-Thin Mobile Phone Cases and Covers Compatibility

Compatibility is a major concern when buying ultra-thin phone cases. A case is typically designed to fit a particular phone model, or in some cases, a particular line of models from the same brand. As cases must correspond to the phone's dimensions and form factor, they are usually not interchangeable. However, as phone dimensions are becoming more or less standard, some covers can be used with multiple models across different brands.
